Description

Optical connector and server using optical connector

The present invention relates to an optical connector, and more particularly to a movable optical connector used when wiring is connected by a plurality of connectors in signal transmission / reception between a substrate and another substrate.

Conventionally, transmission of signals between LSIs such as processors, other application-specific integrated circuits (ASICs), memories, storage devices, and related electronic circuit units, or LSI-backplanes in information devices such as routers and servers Has been made by electrical signals through electrical wiring and substrate wiring. However, with the recent increase in functionality of MPU (Micro Processing Unit), the amount of data exchange required between semiconductor chips has increased remarkably, and as a result, various high frequency problems have emerged. Therefore, an optical signal transmission method with high speed and less crosstalk and noise has been adopted. In recent years, adoption of this optical signal transmission system has been studied for transmission of signals between unit substrates on which these LSIs and the like are mounted.

Special table 2011-520151

As described above, when an optical signal transmission method is adopted for signal transmission between unit boards, an optical signal from an optical transmission / reception module that performs photoelectric conversion (or electro-optical conversion) is formed when an optical signal transmission system is configured. The connection method between optical connectors connected to one end of the transmitting optical fiber or the optical waveguide becomes a problem.

In order to increase the practicality by optically connecting the optical connector and the optical connector, which are the exits of the optical signal output from the unit substrate having the LSI and electrical wiring laid on the substrate, with sufficient accuracy, the first In addition, it is necessary that the optical axis alignment between the optical connector and the optical connector composed of a plurality of optical fibers or optical waveguides can be achieved with sufficient accuracy. The allowable amount of optical axis deviation is, for example, 20 μm or less when the optical transmission line such as an optical fiber or an optical waveguide is a multimode optical waveguide. Secondly, considering mass production of products, it is necessary to be able to position and fix with high workability and high accuracy without performing complicated optical axis adjustment work. Third, from the viewpoint of ease of equipment maintenance and renewal, when replacing the unit board, connection on which means coupling of optical connectors or connection off which means disconnection of connections can be easily performed, and there is a failure part. It is necessary to easily replace only the unit substrate.

As a structure for connecting an optical connector and an optical connector, there is known a method of fitting using a guide pin or a housing. FIG. 18 is a schematic cross-sectional view of a widely used optical connector. In this conventional example, as shown in FIG. 18, the connection is made using guide pins or housing guides attached to the optical connector. In this structure, the optical connector and the optical connector are automatically aligned without adjustment by a so-called fitting method. Therefore, the first requirement and the second requirement can be satisfied.

Also, a method of connecting an optical connector and an optical connector using a magnet as an alignment mark is known (for example, see Patent Document 1). In this conventional example, a magnet is mounted on one connector. The magnet also has a function as an alignment mark for performing high-precision alignment between the connector and the connector. By using this magnet, the optical connector and the optical connector are optically coupled. Also in this structure, since the optical axis alignment of the optical connector and the optical connector is automatically achieved without adjustment (self-alignment), it is possible to satisfy the first requirement and the second requirement.

However, in the method disclosed in the general-purpose product, since the optical connector is connected along the housing or the guide pin, when a plurality of optical connectors for large-capacity transmission / reception are connected on or off In addition to pressing force or pulling force, it is necessary to release the connector connection state, and it is difficult to turn the connection on and off by a simple method. Therefore, this conventional example does not satisfy the third requirement.

Further, in the conventional optical connector device, since the connection between the plurality of unit boards is performed via the inter-substrate wiring formed on the rear substrate, connection between a large number of circuit elements is particularly required. In a parallel processing apparatus or the like, the number of wirings in a board and between boards increases, and the increase in the number of wirings causes a problem of wiring congestion and mutual interference between wirings. In addition, the cooling system for cooling the unit board may not function due to wiring congestion. Further, the connection between the unit substrates via the inter-board wiring formed on the back substrate causes an increase or variation in the inter-circuit element wiring length, which causes an increase in signal delay and a clock skew.

Further, in the magnet connection method described in Patent Document 1, since there is no mechanism for releasing magnets, connection can be performed, but in order to disconnect the connector connection, a mechanism for releasing the magnet connection is required. This increases the scale of the device due to the addition of complex mechanisms. That is, this conventional example does not satisfy the second requirement. For this reason, in the structure of this conventional example, when a defect occurs in the semiconductor element, all unit substrates contained in the rack are forced to be replaced, so that the effective maintenance cost becomes high.

As described above, since the conventional technology cannot satisfy all the first to third requirements, a plurality of optical connectors between unit boards on which LSIs and the like are mounted with good workability and low cost. Are optically connected with sufficient accuracy, and there is a problem that an optical connector device having high practicality and good maintainability cannot be provided.

In order to solve the above-described object, an optical connector of the present invention is, for example, an optical connector including a first connector member and a second connector member, and the first connector member includes a housing and a housing. An optical fiber through-hole, a fixing portion for fixing the optical fiber provided in the housing, and a first alignment portion provided on the surface of the housing, and the second connector member includes a housing An optical fiber through hole passing through the housing, a fixing portion for fixing the optical fiber provided in the housing, and a second alignment portion provided on the surface of the housing, the first alignment portion A magnet is provided in a portion connected to the second alignment portion on the surface of the first, a magnetic body is provided in a portion connected to the magnet on the surface of the second alignment portion, the magnet of the first connector member, By connecting the magnetic body of the 2 connector member, By connecting the member members together, the optical fiber fixed to the first connector member and the optical fiber fixed to the second connector member are optically connected. It further has a shielding means.

In the fifteenth embodiment of the present invention, an optical connector device having a magnetic shielding means and having a self-alignment magnet mechanism will be described. The magnetic shielding means referred to in this specification means means for weakening the magnetic force acting between the magnet and the metal. The configuration in which this means is realized will be described in each embodiment.

Hereinafter, configurations and operations of various embodiments according to the present invention will be described with reference to the drawings. In the drawing, an optical fiber is used as an optical transmission medium. In the description of the drawings, the same elements are denoted by the same reference numerals, and redundant description is omitted. Further, the dimensional ratios in the drawings do not necessarily match those described.

First, the configuration of an optical connector with magnetic shielding means according to an embodiment of the present invention will be described with reference to FIG. 1A and 1B are configuration diagrams of an optical connector device according to the present embodiment, where FIG. 1A shows a connector connection state, and FIG. 1B shows a connector disconnection state. FIG. 2 is an enlarged view of a connection portion between the connectors in FIG. 1, (a) shows a connection state between the magnet and the magnetic material, and (b) shows a separation state between the magnet and the magnetic material.

As shown in FIG. 1, the connector member A is composed of a connector housing and a receptacle which is an alignment unit. A through hole for passing an optical fiber and a fixing portion for fixing the optical fiber are provided in the connector housing. Similarly, the connector member B includes a connector housing and a receptacle. Further, for example, since the receptacle is configured to fit on a rail attached to the connector housing, the receptacle can be freely moved out and retracted with respect to the connector housing. It has become. With this structure, even when the connector member A and the connector member B are fixed to a server blade or the like, the connection on state can be realized by moving only the receptacle from the connection off state between these connectors.

As described above, one of the receptacles of the connector member A and the connector member B has a magnetic shielding means, and a magnet is provided instead of the alignment mark. Both connector members are aligned by the attractive force between the magnet and a magnetic material such as metal, and the connected state is maintained.

Further, lenses 11a and 11b are attached to the connector member A and the connector member B, respectively. With this lens, for example, the light emitted from the connector optical fiber becomes collimated light having an enlarged beam size, propagates through the space, and when the light is input to the optical fiber, the enlarged light beam is condensed by the lens 11b. And coupled with the optical fiber. As a result, the connection tolerance accuracy between the connector member A and the connector member B is increased 10 times or more, and is less susceptible to dust and dirt in the atmosphere.

As shown in FIG. 1A, the connector state of the connector member A and the connector member B is maintained by the magnet mechanism, and the connector member A and the connector member B are held by the magnetic shielding means as shown in FIG. Is cut off.

An optical signal has a bandwidth by encoding information in a plurality of frequency components of light transmitted along one optical fiber or a waveguide using wavelength division multiplexing (Wave Division Multiplexing: WDM). It may be enhanced. In a dense configuration, the optical transmission medium may comprise a plurality of optical fibers or waveguides. Thereby, each optical fiber or waveguide carries a WDM signal and realizes a high bandwidth per unit area.

Next, the magnetic shielding means will be described. FIG. 2 explains the details of the connection location between the connectors shown in FIG. As shown in FIG. 2A, the magnet 22 has a structure capable of rotating. It can be controlled manually. Specifically, when the straight line connecting the N pole side and the S pole side of the magnet is parallel to the magnetic material, the lines of magnetic force enter the magnetic material through the yoke 21, and therefore the attractive force between the magnet and the magnetic material. Works, and the magnet and the magnetic material are attached. On the other hand, as shown in FIG. 2B, when the straight line connecting the north and south poles of the magnet is perpendicular to the magnetic material, the magnetic force lines cannot enter the magnetic material and the magnet and the magnetic material are separated. It becomes a state. Thus, by rotating the magnet, the magnet and the magnetic material can be connected and disconnected. 1A and 1B illustrate a case where this mechanism is employed.

As shown in FIG. 1, the movement of the connector member A and the connector member B is in the x, y, z directions, the inclination angles, and the rotation angles θa, θb, θc, respectively, and the connection between the connector member A and the connector member B is Alignment adjustment is performed with high accuracy so as to achieve a highly efficient optical coupling state.

The optical fiber 1 fixed to the first connector member A and the optical fiber 1 fixed to the second connector member B are optically connected, and the first alignment is performed. The part 3 further includes magnetic shielding means.

According to the first embodiment, since the magnet terminal to be the alignment mark can be formed by patterning, it can be formed with high precision. Since the patterned magnets are in contact with each other, a force is automatically exerted in a direction to correct the misalignment. Since it is not necessary to adopt a special means for high precision connection of the connector, it is possible to save the connector space.

Hereinafter, the same reference numerals used in different drawings indicate similar or identical elements.

First, with reference to FIG. 3, the overall configuration of a connector with magnetic shielding means according to an embodiment of the present invention will be described. 3A and 3B are configuration diagrams of the optical connector device according to the present embodiment, where FIG. 3A shows a state before connector connection, and FIG. 3B shows a state after connector connection.

As shown in FIG. 3 (a), the connector member 102 and the connector member 108 achieve high-efficiency optical coupling by combining a magnet that also serves as an opposing alignment mark and a magnetic material. That is, as shown in FIG. 3A, the mark 103a on the connector member 102 side and the mark 106a on the connector member 108 side, and similarly 103b and 106b, 103c and 106c, 103d and 106d, 103e and 106e, 103f And the alignment marks 106f are matched to achieve high-precision optical connector connection. In addition, as shown in FIG. 3B, the connection state between the connector member 102 and the connector member 108 is held, for example, by the attractive force of the magnet and the magnetic material in the magnet mechanism.

As shown in FIG. 3B, signal exchange between the optical transceiver modules is performed as follows. A signal generated from the optical transmission / reception module 101 is transmitted through the optical fiber 109, passes through the connector member 102 and the connector member 108 connected in a highly efficient optical coupling state, and then again passes through the optical fiber 109 to the opposing optical transmission / reception module 101. Sent and detected.

As for the magnetic shielding means, for example, the mechanism shown in the first embodiment may be applied to the receptacle (not shown), but the magnetic shielding means is not limited to this.

First, with reference to FIG. 4, the overall configuration of the apparatus showing inter-substrate signal exchange using the connector with magnetic shielding means according to one embodiment of the present invention will be described. FIG. 4 is a block diagram showing signal transmission / reception between substrates using the optical connector according to the present embodiment.

As shown in FIG. 4, a signal from an electronic component 185 such as a CPU or a memory controller mounted on the substrate 150 and an electronic component 185 such as a CPU or a memory controller mounted on the substrate 151. Signal transmission and reception is as follows. An electrical signal from the electronic component 185 of the substrate 150 is first sent to the optical module 184 through the wiring 183, and is converted into an optical signal by performing an electrical-optical conversion in the optical module 184, and then transmitted through an optical fiber. After being sent to the optical fiber again through the optical connector members 161 and 166 and subjected to optical-electrical conversion by the optical module 184 and converted into an electrical signal, the CPU mounted on the other board 151 It is sent to an electronic component 185 such as a memory controller. In this way, signal transmission / reception is realized by optical signal transmission / reception between electronic components mounted on different substrates.

As described above, large-capacity signal transmission / reception is realized by performing signal transmission / reception between electronic components mounted on different substrates using optical wiring using a plurality of optical connectors. That is, even through the optical connector members 162 and 165, large-capacity signal transmission / reception is realized by performing signal transmission / reception between electronic components mounted on different substrates using optical wiring. Similarly, large-capacity signal transmission / reception is realized by performing signal transmission / reception between the electronic components mounted on different substrates through the optical wiring also through the optical connector members 163 and 164. In general, the number of optical connectors increases as the capacity of signals to be processed increases.

The movement of the connector members 161, 162, 163, 164, 165, and 166 becomes the x, y, z directions, the inclination angle, and the rotation angle θ as shown in FIG. The connection is aligned with high accuracy so as to be in a highly efficient optical coupling state. Similarly, the connection between the connector member 162 and the connector member 165 and the connection between the connector member 163 and the connector member 164 are made with high accuracy.

Regarding the magnetic shielding means, for example, the mechanism shown in the first embodiment may be applied to the receptacle (not shown), but the shielding means is not limited to this.

First, with reference to FIG. 5, the overall configuration of the apparatus showing inter-substrate signal transmission using the connector with magnetic shielding means according to one embodiment of the present invention will be described. FIG. 5 is a block diagram showing signal transmission / reception between boards using the optical connector device according to the present embodiment.

As shown in FIG. 5, a signal from an electronic component 185 such as a CPU or a memory controller mounted on the substrate 150 and an electronic component 185 such as a CPU or a memory controller mounted on the substrate 151 Signal transmission and reception is as follows. An electrical signal from the electronic component 185 of the substrate 150 is first sent to the optical module 184 through the wiring 183, and is converted into an optical signal by performing an electrical-optical conversion in the optical module 184, and then transmitted through an optical fiber. Then, it is transmitted again through the optical fiber via the optical connector members 161 and 166, and is converted into an electrical signal by the optical module 184, and is then mounted on the other substrate 151. It is sent to an electronic component 185 such as a CPU or memory controller. In this way, signal transmission / reception is realized by optical signal transmission / reception between electronic components mounted on different substrates.

In this way, signal transmission / reception between electronic components mounted on different substrates is performed by first collecting signals at the substrate end and then connecting the optical connector members 161 and 162.

As shown in FIG. 5, the movement of each connector member is in the x, y, z direction, the inclination angle, and the rotation angle θ, and the connection between the connector member 161 and the connector member 166 is in a highly efficient optical coupling state. Alignment is performed with high accuracy. Similarly, the connection between the connector member 162 and the connector member 165 and the connection between the connector member 163 and the connector member 164 are also performed.

Regarding the magnetic shielding means, for example, the mechanism shown in the first embodiment may be applied to the receptacle (not shown), but the shielding means is not limited to this.
