DESCRIPTION

Device for the adaptation of optical ports Object of the invention

The present invention is intended to present a device (called an adaptation set or adaptation device) that allows an optical port (also called an optical receptacle or optical fiber port) to be adapted of a certain type (thread, bayonet or any other) so that be compatible with a basic universal connector. These robust optical ports (also called reinforced) are, for example, the ports of the optical terminal boxes deployed in a fiber optic access network to service the user.

Background of the invention

In an optical fiber communications system, fiber optic connectors are available to interconnect the ends of two optical fibers (that of the connector and for example that of an optical port), so that the optical energy output through an optical fiber The transmission can be optimally coupled to an optical reception fiber. In the development of fiber optic technology, many manufacturers provide different configurations of an fiber optic connector with the purpose of guaranteeing low losses, low cost and ease of assembly.

Thus, there are several types of optical connectors and among them (these are just a few examples since there are many other types of optical connectors):

- The Subscriber Connector or SC connector (“Subscriber Connector” or “Square Connector” in English) is a snap connector, with a ferula (also called “ferrule” of its English denomination) of 2.5 mm., Standardized in TIA -568-A and widely used for its excellent performance.It connects with a simple insertion movement that binds the connector.And it also exists with a duplex configuration.It is widely used in SM installations (English Single Mode, in single mode Spanish) and Network and CATV applications.

- The LC connector: it is a small form factor connector that uses a ferula of

1.25 mm., Half the size of the SC. It is a connector that uses in shape

standard a ceramic splint, easy termination with any adhesive. Good performance, highly favored for single mode use. Used especially in transceivers and communication equipment of high data density.

In turn, the use of the acronyms PC, APC and UPC indicates a type of physical connection: by Physical Contact or PC ("Physical Contact" in English), Connection with angles of inclination at the tip or APC ("Angle Physical Contact "In English) and connection of very low losses or UPC (" Ultra Physical Contact "in English). Thus, for example, we speak of an SC / APC connector.

The robust outdoor connectors allow a quick and safe connection between an optical connection cable and an optical terminal box (specifically, with an optical port of this optical terminal box). In this way it is possible to give continuity to the operator's access network, from the optical terminal box located outside (facade, or post) to the address of the client / user. Currently, in order to register customers who depend on outdoor optical terminal boxes, operators use optical connections with a robust connection with different preset lengths, depending on the distance from the customer's address to the box from which the service is provided.

Operators, for different reasons, may have deployed optical terminal boxes with different types of reinforced optical ports, each for connection with different types of robust optical outdoor connector. Additionally, an operator can use more than one type of connector, a priori, incompatible with each other. This forces operators to have different types of connections and within each type, different lengths each with different robust connectors; which means that operators must manage a wide variety of optical elements, with different logistic codes ... which is a complex task, which generates difficulties in supplying and storing the material.

In addition, this also makes it difficult for the technicians who perform the installation of the client registration, as they need to have different types of connections depending on the terminal box from which the service is to be provided.

To solve the existing problems, the need for a technical solution that allows the adaptation (even in the field) of a wide range of different types of ports or optical receptacles to a common one (also called universal), so that it can be given

service from any type of box, once your receptacle or optical port has become a universal one. This allows to facilitate the logistics and the work of the installer to be able to register with a unique type of optical connection while ensuring a fast, simple and reliable method of assembly.

Description of the invention

The present invention serves to solve the aforementioned problems, solving the problems presented by the solutions of the state of the art, by means of a mechanical device (called assembly or adaptation device or adapter) that allows converting an optical port or receptacle of a certain type (thread, bayonet or other) in one (universal) compatible with a basic universal connector, or more specifically with a base optical unit (also called universal base optical unit) of a robust (reinforced) connector.

In other words, the proposed solution allows the adaptation, by means of adaptation assemblies such as that described in the present invention, of an optical cable (terminated in said unit) to different types of robust (reinforced) ports of the deployed optical terminal boxes. In this way, with a unique type of cable pre-terminated at the factory (assembled to the base optical unit), it can be serviced from boxes with a wide variety of different types of optical ports. Thus, with the solution proposed in the present invention, different types of ports or optical receptacles are compatible with a single optical connection element (by allowing the connection with a wide variety of different types of optical ports with the same optical unit) ) facilitating the work of the technicians who perform the installation of the client registration, making assembly and connection more efficient and simplifying management (for example, by significantly reducing the amount of logistics codes to be managed by the operator).

Specifically, in a first aspect there is a mechanical device that can be coupled to an optical (reinforced) port of an optical terminal box, for adapting said optical port to a basic optical (universal) termination unit of an optical fiber cable. The optical terminal box may belong, for example, to an optical fiber access network. The device comprises:

- an alignment hood that extends longitudinally between a first end and a second end. The first end of said alignment hood will remain inside the optical port when the device is coupled to said optical port and the second end of said alignment hood is where the base optical unit will be introduced for connection with the optical port;

- an anchor cap mounted on the second end of the alignment hood, where the anchor cap includes means for anchoring (connecting) the device to the optical port.

These anchoring mechanisms to the optical port included in the anchoring cap will be of the appropriate type to connect (anchor) to the optical port or in other words, they will be of the appropriate type to connect (anchor) the device to the optical port that you want to adapt. Thus, for example, said anchoring means can be bayonet type connection (if the optical port is bayonet type connection) or threaded connection (if the optical port is thread connection), although of course this is only two examples and any other type of connection of these anchoring means is possible.

In addition, the alignment hood may include anchoring (connection) means for anchoring the device to the base optical unit. These means for example can be at least one flange (although any other means of anchoring is possible). Said flanges will be anchored to corresponding emptyings existing in the base unit (for example, in its main rod)

The device may also include a retaining or holding ring to hold together the different parts that make up the device, a seal (toric) and a plug attachable to the device (for example, to the second end of the alignment hood) to protect the device and the port from damage and dust ingress when the base unit is not connected; This plug will be removed when you want to connect the base unit to the device. The alignment hood may include a groove on which the fastening or retaining ring will be positioned for fixing.

The base optical unit may have a main rod (elongated, for example, cylindrical, hexagonal or pentagonal or any other external shape) and normally the alignment hood has an internal shape coinciding with the external shape of said rod

Said base optical unit may be of any type, for example, said base optical unit may be that described in utility model ES1184287 (application number U201730550) of which this patent claims priority. In that specific case, said base optical unit would include:

- an optical plug which in turn comprises a housing, a ferula (arranged at least partially inside the housing), where the fiber optic cable is attached, and a support piece with anchoring means to a main rod of the optical unit base and with a protruding part that is inserted into the main stem; The optical plug can also comprise a spring that guarantees contact in connection with the ferula of the opposite port / connector;

- the main rod that extends longitudinally between a first end and a second end, being anchored to the optical plug at its first end and being traversed end to end by the fiber optic cable that is inserted at its second end; where the main rod comprises an insert located at its second end where the fiber optic cable is secured by a crimping operation, a locking ring that protrudes over the main rod (to prevent longitudinal displacement of the adaptation assembly in which this introduced the main stem;

- a crimping ring coupled at the second end of the main rod (to secure the fiber optic cable in the main rod by crimping on the cover of the fiber optic cable introduced by said end);

- a protector (thermo-shrink) mounted covering the second end of the main rod, on the crimping ring and on a portion of the optical cable (to protect and provide sealing between the cable and the main rod);

- a protective boot mounted covering part of the main rod and on the thermo-shrink guard (protecting the base optical unit from side loads);

where the base optical unit includes anchoring means (for example, in the main rod or in the housing of the optical plug) for anchoring with the adaptation set that allows connection to different types of optical ports.

As indicated, the main rod may include one or more recesses (gaps or recesses) where the different adaptation sets are anchored by means of tabs on the base optical unit when the base optical unit is connected to the port. It can also include a flat gasket to allow the recoil of one or more anchor assemblies of the different adaptation assemblies onto the main rod until the tabs of the adaptation assembly into which the base optical unit is inserted are actuated and fixed.

Detailed description of the invention

Examples of realization of the invention are described below in detail, mentioning when necessary the above-mentioned figures, without limiting or reducing the scope of protection of the present invention.

The adaptation assemblies described in the present invention are responsible for converting (adapting) a certain type of receptacle or optical port into an optical port of another type, which we could call universal. That is, the adaptation assemblies, once coupled (mounted) to the optical port or receptacle included in the outdoor optical terminal boxes, convert the different ports or receptacles into a universal receptacle or port compatible with a type of universal connector, which here is called basic universal connector or base optical unit. From another point of view, it can be said that the adaptation assemblies once the base optical unit is introduced into them allow the connection of the optical unit with an optical port (also called the optical fiber port) of a certain type.

The assembly of said adaptation assemblies is quick and simple and no element of the port or receptacle must be removed from the box. In any case, it is only necessary to remove the protective cap from the reinforced port and put in place the adaptation set.

The adaptation sets can be of different types depending on the type of optical port they want to adapt (make universal). Thus, the adaptation set can be designed to be coupled to a bayonet reinforced port, to a threaded anchorage port, to a hexagonal reinforced port, SC / APC port or any other type.

In one embodiment, the adaptation assemblies may comprise a first piece, alignment hood (which usually has an internal shape coinciding with the external shape of the base optical unit with which it is compatible for better coupling) and a second piece, cap anchor, mounted on one end of the alignment hood. The anchoring cap will have suitable anchoring (connection) mechanisms (for example bayonet type or by thread) to anchor to the optical port. The adaptation set may be provided with at least one flange to be anchored to the base optical unit with which it is compatible.

The base optical unit (also called the base optical device) will preferably be factory mounted on a fiber optic cable (also called an optical cable) for outdoor connection, suitable for weather conditions. In one embodiment, said optical unit would incorporate all the optical components necessary to make an optical connection, however, it would normally not include any mechanical element that allows it to be anchored and unpinned to an optical confronter (such as an optical port) of the most common types of a proper way. But you would need to add one of the adaptation sets proposed in the present invention to be able to connect to any type of port properly. That is, it is the adaptation set that includes the means to perform the mechanical anchoring with the reinforced type ports (bayonet, threaded ...) providing the optical unit with mechanical retention base (and weather protection).

In one embodiment, said base optical unit with which the proposed adaptation sets will be compatible, is that described in utility model ES1184287 of which this patent claims priority (this is only a non-limiting example, and another type of base optical unit with other forms and components are possible). Although the base optical unit is not properly part of the invention proposed in the present utility model, for a better understanding, a view of said base optical unit (100) with all its components assembled is shown in Figure 1. In figure 1 (main body) used is

pentagonal, but this is just a non-limiting example. The stem of the proposed base optical unit may be of any other known form, for example and without limitation, hexagonal or cylindrical.

In general, the base optical unit is composed of several duly assembled elements that, together with the external supply cable, form a set that allows the optical continuity of the cable to the connector splint. In the example of Figure 1, said components would be an optical plug (101) with a ferula attached to an optical fiber cable, a rod (102) also called a main rod, a protective boot (103), a heat-shrinkable protector (104) and a crimp ring that is not seen in Figure 1 as it would be under the protective boot (it should be noted that this is only a realization of the non-limiting invention and that not all of these components are mandatory. Some of these components are optional and in other embodiments additional components may not appear and / or appear All these parts are preferably assembled at the factory in order to simplify the assembly process.

As indicated above, the adaptation sets can be of different types depending on the type of optical port they want to adapt (to which they want to couple / connect). Thus, the adaptation set can be designed to be coupled to a bayonet reinforced port, to a threaded anchorage port, to a hexagonal, SC or any other type reinforced port. It would be possible to define a multitude of adaptation sets for different types of optical port, but by way of example and illustration, only some possible embodiments are included (although of course, other types of assemblies that adapt other types of optical ports are possible to be compatible with a universal base optical unit).

- Bayonet reinforced port adaptation set:

This adaptation set consists of a set of parts (preferably plastic although they can be made of another material), which are designed so that once coupled on an optical receptacle or bayonet type port, they turn it into another type of optical receptacle or port compatible with a certain type of universal optical connector (base optical unit) of smaller dimensions.

A bayonet connection, also called bayonet closure or bayonet mounting, is a type of quick coupling and attachment mechanism between the intercorresponding surfaces of two parts or devices. One of them, called "male" has one or more pins or projections that fit the receiving surface or "female", where slits and a spring or spring maintain the clamping force. To couple the two surfaces, it is necessary to align and fit by pressing, the projections of the male surface with the grooves of the female surface.

Figure 2 shows a view of this adaptation set compatible with a reinforced bayonet type port according to an embodiment of the invention. In said embodiment said adaptation set (200) is composed of the following elements shown in Figure 3 (this is only an exemplary embodiment, some of these components are optional and in other embodiments of the base optical device may not appear and / or appear additional components):

An anchoring cap (connection) type bayonet (203) arranged on the alignment hood (205), which will allow the anchoring and the subsequent connection to the corresponding port, by means of a bayonet type connection.

An alignment hood (205) adapted to the bayonet type optical receptacle. In the concrete design shown in the figure, the alignment hood has a longitudinal opening at one of its ends, but this is not fundamental to the invention being described here. This end of the alignment hood will be inserted into the port when the device is attached to the port. As will be explained later, this element, among other things, will allow the fitting and connection between the adaptation set and the universal connector (base optical unit). Additionally, it can incorporate a groove (2052), on which a fastening or retention ring (201) will be positioned. The internal shape (or the internal diameter if cylindrical) of the retaining ring must be adapted to the shape of this recess or groove that incorporates the alignment hood. In this way the ring is locked in the position of the groove, and prevents displacement in a longitudinal direction of the anchoring cap (203). The design of the alignment hood allows the anchoring cap to be positioned on a part of it and limits its longitudinal and rotation or rotation movements.

As indicated above, the adaptation set can also have a fastening ring (201), also called a retention ring (which holds together the different parts that make up the adaptation set), a spring (204) and a toric seal gasket (202). The anchoring cap can slide partially longitudinally over the alignment hood, limited in both directions, on the one hand by the alignment hood itself and on the other with the retaining or holding ring.

A plug (206) adapted to the shape of the adaptation assembly can also be used to close it when there is no base unit attached thereto. This plug does not necessarily have to be part of the adaptation set, it is simply a plug to cover the adaptation set (and therefore the port to which it is attached), when the base unit is not connected to the port, to protect it mainly from the dust inlet.

All these parts are usually presented assembled at the factory in order to simplify the assembly process to the corresponding port.

In one embodiment, said alignment hood (205) incorporates a mechanism of at least one flange or click, 2051, (in the specific case of the preferred embodiment would be 2 tabs) that allow its anchoring with a certain type of connector (universal) which is compatible with the inner receptacle that incorporates the alignment hood. This is only a non-limiting example and in other embodiments the anchoring with the optical connector may be by another mechanism. In one embodiment, said compatible connector will be the base optical unit shown in Figure 1. Specifically, said alignment hood can be anchored to the main stem (102) of the base optical unit. Specifically, said clicks / tabs (2051) of the adaptation set will anchor the adaptation set to the recesses (1021) included in the body of the main rod of the base optical unit, when the main rod of the base optical unit is insert inside the alignment hood (of the device) for connection to the port.

It should be noted that as indicated, the base optical unit when it is anchored to the reinforced adaptation assembly (bayonet type or any other type) normally has the necessary sealing / sealing conditions that allow its use in

weathering and withstands significant mechanical stresses (typically defined for reinforced connectors and ports).

In addition, the internal shape of said alignment hood can coincide (or at least be as adapted as possible) with the external shape of the universal connector (of its main stem in the case of the base optical unit shown in Figure 1) to allow the universal connector compatible with it will fit and place only in the correct position. In one embodiment, the internal shape will be pentagonal so it will fit it into pentagonal stems like the one shown in Figure 1, although of course other types of external forms of the universal connector (and in particular of stem forms) and, consequently , internal shapes of the alignment hood are possible.

To mount the adaptation set in the receptacle or optical port (or what is the same to convert a certain bayonet type port or receptacle to a universal type receptacle or port), the adaptation set will be introduced in the appropriate position in the receptacle to the required position and the anchor cap will be rotated until the adaptation assembly is fully anchored on the bayonet-type receptacle or optical port.

- Adaptation set to reinforced optical port with screw anchor:

This adaptation set consists of a set of parts (preferably plastic although they can be made of another material), which are designed so that once coupled (coupled the assembly) on an optical receptacle or threaded type port, they become another type of optical receptacle or port compatible with a certain type of optical connector (base optical unit) of smaller and universal dimensions.

In Figure 4 a view of this adaptation set compatible with a reinforced threaded port according to an embodiment of the invention can be seen. In said embodiment said adaptation set (300) is composed of the following elements shown in Figure 5 (this is only an exemplary embodiment, some of these components are optional and in other embodiments of the base optical device may not appear and / or appear additional components):

An anchor nut (with thread type connection) (302) arranged on one end of the alignment hood (304), to allow anchoring and connection to the corresponding receptacle or port by means of a thread type connection. This nut can also be called anchor cap as in the previous case.

An alignment hood (304). Among other things, this element will allow the fitting and connection between the adaptation set and the universal connector (base optical unit) with which it is compatible. In addition, one end of the alignment hood (as can be seen in Figures 7, 8 or 9) will be inserted into the port when the device is attached to the port. Additionally, it can incorporate a groove (3042), on which a fastening or retention ring (301) will be positioned. The internal shape or the internal diameter in case of being cylindrical, of the retaining ring must be adapted to the shape of this recess or groove that incorporates the alignment hood. In this way the ring is locked in the position of the groove, and prevents displacement in a longitudinal direction of the nut (302). The design of the alignment hood allows the anchor nut to be positioned on a part of it and limits its movements longitudinally, allowing it to rotate freely.

As indicated above, the adaptation set can also have a fastening ring (301), also called a retaining ring (which holds together the different parts that make up the adaptation set) and a toric sealing gasket (303 ). The anchoring cap can slide partially longitudinally over the alignment hood, limited in both directions, on the one hand by the alignment hood itself and on the other with the retaining or holding ring.

A plug (305) adapted to the shape of the adaptation assembly can also be used to close it when there is no base unit attached thereto. This plug does not necessarily have to be part of the adaptation set, it is simply a plug to cover the adaptation set (and therefore the port to which it is attached), when the base unit is not connected to the port, to protect to the whole mainly of the dust inlet.

All these parts are usually presented assembled at the factory in order to simplify the assembly process to the corresponding port.

In one embodiment, said alignment hood (304) incorporates a mechanism of at least one flange or click, 3041, (in the specific case of the preferred embodiment would be 2 tabs) that allow its anchoring (connection) with a certain type of connector Optical (universal) that is compatible with the inner receptacle that incorporates the alignment hood. This is just a non-limiting example and in other embodiments the anchoring with the connector can be by another mechanism. In one embodiment, said compatible connector will be the base optical unit shown in Figure 1. Specifically, said alignment hood can be anchored to the main stem (102) of the base optical unit. Specifically, said clicks / tabs (3041) will anchor the adaptation set to the recesses (1021) included in the body of the main rod of the base optical unit, when the main rod of the base optical unit is inserted inside of the alignment hood (of the device) for connection to the port.

In addition, the internal shape of said alignment hood normally coincides (or at least is as adapted as possible) with the external shape of the universal connector (of its main stem in the case of the base optical unit shown in Figure 1) to allow the universal connector compatible with it will fit and place only in the correct position. In one embodiment, the internal shape will be pentagonal so it will serve to fit it in pentagonal rods such as that shown in Figure 1, although of course other types of external shapes of the universal connector (and in particular of stem shapes) and, consequently , internal shapes of the alignment hood are possible.

To mount the adaptation set in the receptacle or optical port (or what is the same to convert a certain threaded type port or receptacle to a universal type receptacle or port), the adaptation set will be introduced in the appropriate position in the receptacle to the required position and the anchoring cap will be rotated so that the adaptation assembly screwed into the port and is fully anchored on the receptacle or optical port type thread.

In one embodiment, when the device is used with the base optical unit shown in Figure 1, the alignment hood (for both the bayonet and thread assembly) will have an outside diameter greater than the outside of a locking ring that incorporates

5

10

fifteen

twenty

25

35

the main rod of the base optical unit and that of the protective boot (103). In this embodiment, thanks to this feature it will be possible to disassemble the optical base device of the adaptation set in the field (although other forms of disassembly are possible). This happens because, if the alignment hood has a larger diameter (or equal) to that of the locking ring and protective boot, it causes other parts of the adaptation set that are mounted at least partially on the hood (such as the anchor cap ) have an internal diameter greater than that of the locking ring and the protective boot, so that, when the fastening ring (201, 301) is removed, the cap can slide over the locking ring and the protective boot in the direction of the Optical cable, to make the hood anchoring eyelashes accessible and to be able to disconnect them and thus undo the base optical unit of the device (although other forms of de-anchoring or disassembly are possible). The outer diameter of the alignment hood and the inner diameter of the anchoring cap are usually as similar as possible, since with a toric joint the two pieces can be sealed.

As indicated, the adaptation set models described above have been included by way of example and illustration, not limitation; It is possible to define numerous other adaptation assemblies to different types of reinforced receptacles (ports) (for example, standard SC / APC ports, hexagonal), said adaptation assemblies will include the necessary means for on the one hand anchoring / connecting to the corresponding reinforced port and On the other hand, it can be coupled and anchored (or in other words, be compatible) with the base optical unit.

As an example, a box (with 8 ports) is shown in Figure 6, where the adaptation sets proposed in the present invention can be used. As seen in the figure, one of the ports has removed the screw plug (601) to be able to attach to the corresponding adaptation set. In the case shown in the figure, the ports would be threaded type, so the adaptation set used would be the threaded type. The adaptation set will be mounted on the corresponding port using the anchoring (connection) means of the port (in this case thread type, so the adaptation set will be introduced in the appropriate position in the receptacle to the required position and will be rotated the anchoring cap) so that the adaptation assembly is fully anchored on the receptacle or optical port type thread, obtaining a universal port or receptacle (compatible with a universal connector) as can be seen in Figure 7. Here, a As an example, mounting on a single port is shown, but for

16

5

10

30

Of course, the same process of assembly of the adaptation set could have been done in all the ports of the box, turning them all into universal optical ports.

In Figure 8, said universal port can be seen (with the adapter device without its plug (305)), where the base optical unit (100) is coupled by means of the corresponding anchoring means (1021) producing the connection between the optical fiber on which the base optical unit (100) and the optical port are mounted. In figure 9, the assembly can be seen once the base optical unit is attached to the universal optical port. As explained, thanks to the design of the adaptation sets and the base optical unit, the procedure for coupling the port with the base optical unit will be quick, simple and reliable. Although it will vary according to the adaptation set that is used, in general, to couple (connect) the base optical unit to the port (through the adaptation set), it is only necessary to slide the base optical unit into the adaptation set (which will be already mounted in the port) until both are anchored internally, usually by means of the mechanism of tabs ("clicks") that incorporate the adaptation sets.

As you can see, thanks to the adaptation set, a port that only supported threaded connectors (figure 6) has been transferred to a universal port (figure 8) where a universal optical connector can be attached (connected).

Next, although the base optical unit is not properly part of the invention proposed here, for a better understanding and by way of example, we will describe in more detail the elements of the base optical unit described in the utility model ES1184287, with which , among others, the proposed adaptation sets are compatible (this is only a non-limiting example, and another type of base optical unit with other shapes and components is possible) according to a realization of it:

- Optical plug (101): It is composed of several duly assembled elements. In

one embodiment, this optical plug is composed of: a housing (a plastic housing

for example as defined in the SC standard, although it can be from any other

known type), a ferula or ferrule preferably ceramic and for example polished

angularly and 2.5 mm in diameter as defined in the SC / APC standard

(although it can be of any other type and size known) where the fiber cable is attached

optics, a spring that guarantees contact in the connection with the ferrule of the connector

opposite and a support piece that allows the fastening of the whole set of pieces between them and also will allow anchoring to the main stem of the base optical device. The design and shape of the support piece can have different shapes, depending on (among other factors) how the anchor is made between the rod and said piece. A possible realization of the optical plug contemplates the possibility that the support piece includes a system of eyelashes (also called "clicks" of the English term) that allows anchoring between it and the main rod. Another possible embodiment of the optical plug contemplates the possibility that the support piece includes a groove that allows anchoring between it and the main rod by means of tabs arranged in the latter.

- Main rod (102): The main rod is a longitudinal piece that allows the optical cable (pre-connectorized) to be tied at one end and the fixing and anchoring of the optical plug at its other end. It also allows anchoring in the base optical unit (100) to the different adaptation sets. Said rod can extend longitudinally in the axial direction of the ferula of the optical pin.

The rod can include an insert (preferably over-injected and metallic, although it can be made of other materials) at one of its ends, which allows the fastening of the reinforcing elements of the optical cable (for example, glass fibers or aramid) on it, usually by a crimp operation. The body of the rod itself may include a locking ring located on the mooring side of the cable which has the function of blocking the movement of the different adaptation sets that can be positioned on the unit (i.e., this ring allows blocking of the longitudinal displacement of the adaptation set arranged on the rod). In one embodiment, this lock is made together with a flat gasket. The body may also include one or more emptyings for anchoring with the different adaptation assemblies that can be positioned on the base device and one or more emptyings for anchoring and fixing the optical pin.

In addition, the rod may include a flat joint that allows the recoil (longitudinal displacement) of the adaptation assemblies into which the rod is inserted, until the clicks (also called tabs) are actuated and fixed. it can be made of some elastic material (for example rubber or any other) that can change in thickness if it is subjected to a sufficient force (for example, the joint could pass, when exerting pressure on it, of a thickness of 1 mm to 0 , 5 mm, although others

thicknesses are possible). This flat gasket is an optional element. It serves to solve the problem that may arise if the manufacturing tolerances of the different elements mean that when assembled, the tabs of the adaptation set never get to be activated, because they do not reach the emptying area where they have to be positioned. This would cause problems in the anchorage between the base optical unit and the adaptation set (to any type of connector). This flat elastic joint, by yielding a little under the pressure of the adaptation set, would make it easier for the eyelashes to reach the emptying area where they should be positioned. Subsequently the board would partially recover the shape, but the eyelashes retain the whole.

The rod may also include the perimeter joints necessary to ensure the seal between the base optical unit and the different adaptation assemblies that can be positioned thereon.

The rod (102) has a cross section with an outer perimeter that can vary, but which in any case will allow the seal between it and the surrounding parts, and inside it longitudinally includes a cavity of a diameter that allows the passage of the optical connection cable through it. The outer main rod shape (102), allows the adaptation assemblies in which the base optical unit is connected, can only be anchored in a certain position.

- Crimp ring: This normally metallic element (also called corrugated ring) allows the optical cable to be tied to the main rod of the device. The ring can be coupled at one end to the rod and seal the assembly by crimping on the fiber optic cable (usually on its cover) introduced by said end. On the one hand, the ring allows the fastening of the reinforcement elements of the cable on the main rod and on the other hand, allows the mooring of the cover on the ring itself.

- Protector (104): Preferably it will be a heat shrink protector. This element is located by covering part of the main rod, on the crimp ring and on a portion of the optical cable. The heat shrink shield provides a seal between the cable and the main rod, sealing the unit in the cable tie zone.

- Protective boot (103): Also called connector boot or simply boot. This element is located covering part of the main stem, and on the thermo-protective

retractable Protects the device against lateral load stresses, giving the whole mechanical consistency.

It should be noted that the aforementioned component elements usually have an inner diameter greater than the given diameter of the fiber optic cable cover, whereby said components can be traversed internally by the fiber optic cable without tearing the cover.
