Description

A kind of optical cable

Technical field

The utility model belongs to the technical field of information transmission equipment, and in particular to a kind of optical cable.

Background technology

Optical cable is very important part in optical communication system, and its is widely used, external diameter is small, in light weight, and has Certain flame-retarding characteristic, mechanical property requirements are moderate and cost is cheap, therefore are usually used in communication equipment between each light delivery module Interconnection, interconnected between each communication equipment in communications equipment room.But optical cable exterior protection layer of the prior art does not have fire resisting Performance, thus it is fragile when encountering fire, and most of optical cable of the prior art is all laid in the wild, so very Easily bitten by toy, especially mouse etc., thus easily cause the damage of optical cable.

Utility model《Optical cable》（Authorization Notice No.：CN 202351474 U）A kind of optical cable of middle introduction, in tightly packaged fiber Outside the cable core of composition, aramid fiber structure sheaf and jacket structure layer are provided with, is provided with jacket structure layer along cable length direction The stretch resistant structure of extension, a shortcoming of this structure is exactly that the wire harness that can be provided is few, is needing mass data transmission When, it is impossible to transmission in time, and do not account for the disaster such as fire prevention, moistureproof, anti-insect bite and injured to caused by optical cable, so, , it is necessary to spend larger energy to go to safeguard during actual use.

The content of the invention

The purpose of this utility model is to provide a kind of optical cable, to solve the problems mentioned in the above background technology.

To achieve the above object, the utility model provides following technical scheme：A kind of optical cable, including oversheath, separation layer, Cable core, described separation layer are arranged on inside oversheath, and described cable core is arranged in the chamber that separation layer is formed, described Separation layer and cable core between be filled with cotton yarn filling part, the structure of described cable core is：Multiple beams of optical fiber coiling is in a reinforcement On part, and wrapped up in the periphery of optical fiber with sheath, described sheath is worked out by organdy.

Preferably, one layer of light-absorbing material layer is also included inside described sheath, described light-absorbing material layer is by glass Cellucotton is made.

Preferably, described oversheath is silica gel sheath, and scribbles fire retardant in the appearance of described oversheath, and One layer of fluorescence coating is also coated with the outer layer of fire retardant.

Preferably, described oversheath uses injection molding, and in injection molding, it is internally provided with one metal wire layer Net.

Preferably, a waterproof layer is additionally provided between described oversheath and separation layer, described waterproof layer is using resistance Water yarn material is made.

Preferably, described optical fiber includes fiber core, and fibre cladding is laid with outside fiber core.

Preferably, it is provided with the anti-bite bur for preventing worm mouse from biting in the periphery of described oversheath, and anti-bite bur Rounding at sharp mouth.

Compared with prior art, the beneficial effects of the utility model are：Multigroup cable core is wrapped in oversheath simultaneously, can The data volume of transmission will be greatly improved, and be favorably improved the efficiency of transmission of data, and wire netting is with the addition of in oversheath, is also increased Anti-bite bur, can be reduced by the risk of insect bite, and also add fire prevention, waterproof measure, substantially increase optical cable existence effect Rate.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in embodiment of the present utility model is entered Row clearly and completely describes, it is clear that and described embodiment is only the utility model part of the embodiment, rather than all Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making creative work premise Lower obtained every other embodiment, belong to the scope of the utility model protection.

As shown in figure 1, a kind of optical cable of the present utility model, its structure are as follows：Separation layer 2 is arranged on inside oversheath 1, cable Core 3 is arranged in the chamber that separation layer 2 is formed, and cotton yarn filling part 4 is filled between separation layer 2 and cable core 3, cable core 3 Structure is：The coiling of multiple beams of optical fiber 31 is wrapped up on a reinforcements 32, and in the periphery sheath 33 of optical fiber 31, and sheath 33 is by glass Glass yarn is worked out.Because optical fiber all can have certain light to be reflected from optical fiber, if in light regardless of reason The material of fine outer wrapping is reflectorized material, then the signal that transmitted in optical fiber can be impacted, so being set inside sheath 33 There is one layer of light-absorbing material layer 34, the light-absorbing material layer 34 is made up of glass fibre cotton.

In the present embodiment, as shown in Fig. 2 optical fiber 31 includes fiber core 311, optical fiber is laid with outside fiber core 311 Covering 312.

Because it is to encounter water unavoidably in construction, in order to prevent moisture content from being impacted to circuit, in oversheath 1 with isolating Be additionally provided with a waterproof layer 5 between layer 2, the waterproof layer 5 is made of water blocking yarn material, such moisture after optical cable is penetrated into, Obstructed by waterproof layer 5, so as to ensure that the drying of cable interior.

After mounting in addition to meeting water, it is also possible to run into big fire, in order to ensure that optical cable is not burned, oversheath 1 selects Material is silica gel sheath, and scribbles fire retardant in the appearance of oversheath 1, sees optical cable in time for convenience, avoids thing Therefore the outer layer in fire retardant is also coated with one layer of fluorescence coating.

After installing out of doors, it will not be bitten unavoidably by the worm mouse of the Nature, in order to reduce the risk that worm mouse bites, oversheath 1 uses injection molding, and in injection molding, it is internally provided with layer of metal silk screen, and is set in the periphery of oversheath 1 There are the anti-bite bur 11 for preventing worm mouse from biting, and rounding at the sharp mouth of anti-bite bur 11, advantage of this is that, worm can be prevented Mouse bites, and adds the intensity of optical cable again, is not easy to damage because of rotating, and even if oversheath 1 ruptures, due to being gone back in internal layer There is woven wire, be unlikely to be broken.

While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art, It is appreciated that these embodiments can be carried out with a variety of changes in the case where not departing from principle of the present utility model and spirit, repaiied Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
