Abstract
The utility model relates to layer-twisted environment-friendly optical cable which belongs to the technical field of optical cable manufacture. The utility model comprises a center reinforcing element, inner conductors, filler, nonmetal reinforcing bands and sheaths. The inner conductors are evenly distributed on the outer portion of the center reinforcing element. The non-metal reinforcing bands are manufactured outside the inner conductors, the nonmetal reinforcing bands are jacketed by the sheaths, and the nonmetal reinforcing bands are filled with the filler. An inner conductor comprises optical fiber, filler and a bundle tube, the optical fiber in the bundle tube is fixed via the filler. The center reinforcing element is made of metal or nonmetal material. The essential structure of layer-twisted environment-friendly optical cable used in the prior market mainly relates to that the bundle tubes are intertwisted outside the center reinforcing element which is filled with a water-resisting compound of no environment-friendly, the steel-aluminum band is vertically jacketed, then a polythene binding sheath is forced out, and the prior art has the problems that the scope of application is restricted, the prior art is not propitious for environment protection, the external diameter is big, the prior art is also not propitious for the flex, construction and laying of optical cable, and the manufacturing cost is higher. The utility model is suitable for being used as an indoor branch line and an outdoor branch line which are used in each city area network, local area network or access network.
Description
Technical field:
The utility model relates to the indoor and outdoor branch line that a kind of Metropolitan Area Network (MAN), LAN (Local Area Network) or Access Network are used, be particularly related to a kind of at the higher place employing metal center reinforcement of requirement of strength, adopt the layer-twisted type environment-friendly optical cable of nonmetal central reinforce member in highfield and lightning protection place, belong to optical cable manufacturing technology field.
Background technology:
At present, our society just enters cybertimes, and along with fast development of information technology, the FTTH business is flourish especially in recent years, has brought market outlook preferably again for the optical communication industry.At present, cable market layer-stranding cable structure mainly is the outer stranded beam tube of central reinforce member, and fills the non-environment-friendly type compound that blocks water, and vertical then Baogang aluminium strip is polyethylene extrusion bonding sheath again, and mainly there is following a few point defect in this kind structure:
1, the scope of application is limited.This structured light cable wrap is drawn together metal reinforcement and the vertical packaging material material of steel aluminium strip, therefore should not use at highfield and electric power lightning protection zone.
2, be unfavorable for environmental protection.The interior ointment of ointment and twisted cable core is non-ep-type material in this structure fiber optic cable loose tube, is unfavorable for cleaning and cleaning, and environment is polluted easily.
3, this structure optical cable adopts the vertical bag of steel aluminium strip, and external diameter is big, is unfavorable for the optical cable bending, and external diameter is bigger, and weight is heavier, is unfavorable for installing and lays.
4, production run complexity.To indulge Baogang band or aluminium strip when sheath is extruded simultaneously, and the lap-joint of steel band (promptly vertical bag is overlapping) to require to use hot melt adhesive material to carry out bonding, prevent the optical cable infiltration.Yet the hot melt adhesive coating processes is difficult to the injection rate IR of quantitative hot melt adhesive, can not guarantee bonding quality very little as injecting; Inject the following several situation that then can occur too much:
(1) hot melt adhesive is to the inner infiltration of composite band overlap joint, and it is bonding that composite band and cable core are produced, and in the optical cable construction handshaking procedure, causes restrictive coating and cable core to be difficult to peel off;
(2) hot melt adhesive oozes out to composite band overlap joint outside, and the composite band surface can form hot melt adhesive and pile up, and cable core can increase greatly by the plug die resistance, the danger that causes cable core to break.After passing through by force, then can form bulge at jacket surface, influence the optical cable presentation quality.
(3) the hot melt adhesive coating processes requires operating personnel must show great attention to hot melt adhesive injection situation, adjusts according to the personal experience.Peopleware and operation fine degree are had relatively high expectations, and the general operation personnel are difficult to be competent at.
(4) in process of production, because hot melt adhesive easily oozes out from the composite band gap, solidify the back and form foam shape thing, through behind the plug die, blow off through hair-dryer, foam shape thing splashes, is scattered and causes environmental pollution.In addition,, vertically wrap the cleaning of often need stopping of platform, tube calibration device, delay the production time, also cause the waste of material easily because hot melt adhesive just can not be recycled once solidifying the back.
5, production cost is higher.This structure cable outer diameter is bigger, and jacket thickness is thicker, causes the sheath consumption to increase.
Summary of the invention:
The purpose of this utility model is: provide a kind of and can be applicable to the chamber of Metropolitan Area Network (MAN), LAN (Local Area Network) or Access Network, inside and outside branch line, especially it is more suitable to use in requiring good bandability, highfield and electric power lightning protection environment, both saved cost, reach simple in structure again, function admirable, easy-to-install layer-twisted type environment-friendly optical cable.
The utility model is to realize above-mentioned purpose by following technical solution:
This layer-twisted type environment-friendly optical cable is made of central reinforce member, inner wire, filling material, non-metal reinforcing band and sheath, it is characterized in that: the outside of central reinforce member is evenly equipped with inner wire, inner wire is shaped on non-metal reinforcing band outward, non-metal reinforcing band is with sheath outward, and filling material is housed in the non-metal reinforcing band.Inner wire is made of optical fiber, filling material and beam tube, and the optical fiber in the beam tube is fixed by filling material.Central reinforce member is that metal or nonmetallic materials are made.
The beneficial effects of the utility model are:
1, applied widely.The central reinforce member of this structure optical cable can adopt metal material, also can adopt nonmetallic materials to make, therefore both applicable to the high place of requirement of strength, again applicable to highfield and lightning protection place.
2, environmental protection.All adopt UNIGEL new green environment protection section bar material with the interior compound of filling of cable core in this structure fiber optic cable loose tube, environmentally safe is easy to clean, and is convenient to install.
3, external diameter is little, and is in light weight, and bending radius is little, is beneficial to install to lay
4, production run is simple.Outside twisted cable core, directly extrude sheath behind the seamless vertical bag fibre reinforced plastics reinforcing band, do not need to overlap, do not need to use any binding material, be easy to moulding.
5, production cost reduces.This structure cable outer diameter reduces, thereby has saved a large amount of sheath materials and wrappage, and production cost reduces.
