Abstract
This utility model relates to a kind of double sheath butterfly optical cable.The optical cable that purpose is to provide can be difficult to impaired when wiring, and can remove oversheath easily when construction.Technical scheme is: a kind of double jacketed cables, including butterfly optical cable, two reinforcements and the butterfly sheath of clad optical fiber and two reinforcements that described butterfly optical cable by optical fiber, is symmetricly set in optical fiber both sides form；It is characterized in that the outside of this butterfly optical cable is also coated with a protection set.
Description
Technical field
This utility model belongs to optic communication transmission technique field, is specifically related to a kind of double sheath butterfly optical cable.
Background technology
Along with FTTx technology and the fast development of industry, the inside cable of various forms and structure occurs, but in peace
During dress wiring, owing to indoor environment is complicated, during wiring, optical cable pulls on ground or corner, rubbing easily causes cable jacket and break
Damage, injure optical fiber, affect communication quality.
Utility model content
Technical problem to be solved in the utility model is to propose a kind of double sheath for above-mentioned the deficiencies in the prior art
Butterfly optical cable, this optical cable can be difficult to impaired when wiring, and can remove oversheath easily when construction.
The technical solution adopted in the utility model is:
A kind of double jacketed cable, including butterfly optical cable, described butterfly optical cable by optical fiber, be symmetricly set in the two of optical fiber both sides
The butterfly sheath composition of reinforcements and clad optical fiber and two reinforcements；It is characterized in that the outside of this butterfly optical cable is also wrapped
Cover a protection set.
Further, it is provided with two tears with butterfly optical cable Parallel Symmetric between described butterfly optical cable and protection set
Rope.
Further, described tear rope is aramid yarn.
The beneficial effects of the utility model are: this utility model extrudes one layer of protection set outside original butterfly optical cable again,
Optical fiber can be protected further, and outer protective jacket easily can be removed under the effect of tear rope, is greatly improved speed of application.
Accompanying drawing explanation
The radial cutaway view of the sheath butterfly optical cable that Fig. 1 provides for this utility model.
Detailed description of the invention
Further illustrate this utility model embodiment below in conjunction with the accompanying drawings.
As it is shown in figure 1, double sheath butterfly optical cables of the present embodiment include butterfly optical cable, described butterfly optical cable is by optical fiber 2, right
Claim be located at two reinforcements 3 of optical fiber both sides and formed by butterfly sheath 1 that is integrated for above-mentioned parts and that be coated with completely；Institute
State optical fiber and be preferably bend insensitive fiber；Described reinforcement is metal or non-metallic material.
Improvement of the present utility model, is the outside cladding protection set 4 at described butterfly optical cable；Protection set is should be noted during injection
Can not be with butterfly optical cable adhesion.It addition, this utility model is provided with tear rope 5, described tear rope preferably 1110 Tekes virtue
Synthetic fibre yarn；This aramid yarn stretches along the length direction of butterfly optical cable, and in the symmetrical parallel tearing groove being arranged at butterfly optical cable.
Described protection set is flat structure, and it is highly preferred is 2.9 ± 0.1mm, and its width is 3.9 ± 0.1mm.
The beneficial effects of the utility model are: this utility model extrudes one layer of protection set outside original butterfly optical cable again,
Protection set, as exhaustion layer, can protect optical cable injury-free in construction, can be protected by protection set as required after construction completes
Stay, or easily remove under the effect of tear rope；Thus in work progress, it is possible to allow workmen relieved lay without
Worry damage optical cable, be greatly improved speed of application.
Above provided by the utility model pair of sheath butterfly optical cable is described in detail, general for this area
Technical staff, according to the thought of this utility model embodiment, the most all will change,
In sum, this specification content should not be construed as restriction of the present utility model.
Claims (3)
1. double sheath butterfly optical cables, including butterfly optical cable, described butterfly optical cable by optical fiber (2), be symmetricly set in optical fiber two
Two reinforcements (3) of side and butterfly sheath (1) composition of clad optical fiber and two reinforcements；It is characterized in that this butterfly light
The outside of cable is also coated with a protection set (4).
2. double sheath butterfly optical cable as claimed in claim 1, it is characterised in that arrange between described butterfly optical cable and protection set
There are two tears rope (5) with butterfly optical cable Parallel Symmetric.
