Abstract

The invention discloses a kind of optical cable, separation layer is arranged on inside oversheath, and cable core is arranged in the chamber that separation layer is formed, and cotton yarn filling part is filled between separation layer and cable core, and the structure of cable core is：Multiple beams of optical fiber coiling is wrapped up on a reinforcements, and in the periphery of optical fiber with sheath, and sheath is worked out by organdy.Because optical fiber is regardless of reason, there will be certain light to be reflected from optical fiber, if being reflectorized material in the material of optical fiber outer wrapping, the signal transmitted in optical fiber can then be impacted, so being internally provided with one layer of light-absorbing material layer in sheath, the light-absorbing material layer is made up of glass fibre cotton.It is an advantage of the invention that：The data volume that can be transmitted will be greatly improved, and be favorably improved the efficiency of transmission of data, wire netting is with the addition of in oversheath, it also add anti-bite bur, it can reduce by the risk of insect bite, and also add fire prevention, waterproof measure, substantially increase optical cable existence efficiency.

Description

A kind of optical cable

Technical field

The invention 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 widely used, external diameter is small, lightweight, and has Certain flame-retarding characteristic, mechanical property requirements are moderate and with low cost, 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, so fragile when encountering fire, and most of optical cable of the prior art is all laid in the wild, so very Easily by toy, especially mouse etc. bites, and thus easily causes the damage of optical cable.

Invention《Optical cable》（Authorization Notice No.：CN 202351474 U）A kind of optical cable of middle introduction, is constituted in tightly packaged fiber Cable core outside, be provided with aramid fiber structure sheaf and jacket structure layer, jacket structure layer in be provided with along cable length direction extend Stretch resistant structure, a shortcoming of this structure is exactly that the wire harness that can be provided is few, need mass data transmission when, no It can in time transmit, and not account for the injury that the disasters such as fire prevention, moistureproof, anti-insect bite are caused to optical cable, so, actually make Used time is, it is necessary to spend larger energy to go maintenance.

The content of the invention

It is an object of the invention to provide a kind of optical cable, to solve the problems mentioned in the above background technology.

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

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

It is preferred that, 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.

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

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

It is preferred that, described optical fiber includes fiber core, and fibre cladding is laid with outside fiber core.

It is preferred that, 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 invention are as follows：Multigroup cable core is wrapped in oversheath simultaneously, can be transmitted Data volume will greatly improve, be favorably improved the efficiency of transmission of data, wire netting with the addition of in oversheath, also add anti- Bur is stung, can be reduced by the risk of insect bite, and also add fire prevention, waterproof measure, optical cable existence efficiency is substantially increased.

Embodiment

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in embodiments of the invention is carried out it is clear, It is fully described by, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.Base Embodiment in the present invention, those of ordinary skill in the art obtained under the premise of creative work is not made it is all its His embodiment, belongs to the scope of protection of the invention.

As shown in figure 1, a kind of optical cable of the present invention, its structure is as follows：Separation layer 2 is arranged on inside oversheath 1, cable core 3 It is arranged in the chamber that separation layer 2 is formed, cotton yarn filling part 4, the structure of cable core 3 is filled between separation layer 2 and cable core 3 For：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 organdy Work out.Because optical fiber all can have certain light to be reflected from optical fiber regardless of reason, if outside optical fiber The material of parcel is reflectorized material, then the signal that transmitted in optical fiber can be impacted, so being internally provided with one in sheath 33 Layer 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 being 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 is selected Material is silica gel sheath, and scribbles fire retardant in the appearance of oversheath 1, sees optical cable in time for convenience, it is to avoid thing Therefore, it is also coated with one layer of fluorescence coating in the outer layer of fire retardant.

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 is bitten, and the intensity of optical cable is added again, is difficult to damage because of rotating, even and if oversheath 1 rupture, due in internal layer and also There is woven wire, be unlikely to fracture.

Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with A variety of changes, modification can be carried out to these embodiments, replace without departing from the principles and spirit of the present invention by understanding And modification, the scope of the present invention is defined by the appended.
