Abstract
A kind of sheath of 8 core fibre arrays of MT, the optical fiber perforation being not communicated with there are two being set in its main body, the width of each optical fiber perforation is just passed through for 4 optical fiber arranged in parallel, 4 optical fiber in the two perforation are discrete in the both sides of sheath, four optical fiber of left and right side in this way are easy to fit inside from four optic fibre holes of fiber termination box Far Left and rightmost, and the case where being less prone to dislocation perforation, the case where misdrawing hole is thus greatly reduced, the efficiency for wearing optical fiber is also greatly improved；In addition, since the perforation of each optical fiber just accommodates four optical fiber, when filling glue carrys out curing optical fiber in optical fiber perforation in this way, so much glue is not just had to, glue is set not flow out that section of optical fiber surface being attached to by sheath from optical fiber perforation and cause this section of optical fiber more fragile, therefore the more reasonable structure of the utility model, helps to improve the service life of 8 core fibres.
Description
Technical field
The utility model is related to a kind of fiber arrays of 8 cores of MT.
Background technology
Current fiber array mainly have 12 cores, two kinds of 8 cores, but the sheath of current MT fiber arrays is the standard that is directed to
Wire jumper and design, that is, exclusively for 12 rather than 8 ribbon fibers and design, as shown in Figure 1, being set in sheath 10
There is the optic fibre hole 101 passed through for 12 optical fiber, so when in use, when sheath is used for being inserted in 12 optical fiber, be filled in sheath
The interior glue for being used for fixing optical fiber is not easy to flow out；But if the sheath of this 12 core uses 8 core fibre 20, as shown in Fig. 2, due to
There are the spatial position for being equivalent to remaining 4 optical fiber, the cement ratio being then filled in sheath more in sheath, it is easy to from this
It is flowed out in extra space, and then leads to flow to the optical fiber surface outside sheath, that section of optical fiber for speckling with glue is caused to be easy to split off；
Moreover, the at this moment poor sealing of this 8 optical fiber, and then affect the signal transmission of optical fiber.
Invention content
The purpose of this utility model is to be to have overcome the deficiencies of the prior art and provide a kind of more reasonable structure, contribute to
Improve the sheath of 8 core fibre service lifes of MT.
In order to solve above-mentioned technical problem, the utility model uses following technical proposals：
A kind of sheath of 8 core fibre arrays of MT, including main body are set in the main body there are two the optical fiber being not communicated with perforation,
The width of each optical fiber perforation is passed through for 4 optical fiber arranged in parallel.
Compared with prior art, the utility model has the following advantages that：The optical fiber being not communicated with there are two being set in main body is worn
The width in hole, the perforation of each optical fiber is just passed through for 4 optical fiber arranged in parallel, the two 4 optical fiber in perforating it is discrete
The both sides of sheath, four optical fiber of such left and right side are easy to pierce into from four optic fibre holes of fiber termination box Far Left and rightmost
The case where going, and being less prone to dislocation perforation, thus greatly reduces the case where misdrawing hole, also greatly improves the effect for wearing optical fiber
Rate；In addition, since the perforation of each optical fiber just accommodates four optical fiber, filling glue carrys out curing optical fiber in optical fiber perforation in this way
When, just do not have to so much glue, glue is made not flow out that section of optical fiber table being attached to by sheath from optical fiber perforation
Face and cause this section of optical fiber more fragile, therefore the more reasonable structure of the utility model, help to improve 8 core fibres uses the longevity
Life.
The utility model is described in further detail with specific implementation mode below in conjunction with the accompanying drawings：
【Description of the drawings】
Fig. 1 is the stereoscopic schematic diagram of traditional 8 core fibre sheaths；
Fig. 2 is the use schematic diagram of traditional 8 core fibre sheaths；
Fig. 3 is the stereoscopic schematic diagram of the utility model embodiment；
Fig. 4 is the use schematic diagram of the utility model embodiment.
【Specific implementation mode】
The utility model is a kind of sheath of 8 core fibre arrays of MT, as shown in figure 3, including main body 1, in the main body 1
If there are two the optical fiber being not communicated with perforation 11, the width of each optical fiber perforation 11 is passed through for 4 optical fiber arranged in parallel, the two
4 optical fiber 2 in perforation are discrete in the both sides of sheath.When the sheath for having worn 8 optical fiber will be encased in fiber termination box, such as Fig. 4
It is shown, it is fitted inside after that four optical fiber in left side are first directed at that leftmost four optic fibre holes 31 of fiber termination box 3 one by one, then will be right
That four optical fiber of side fit inside after being also directed at four optic fibre holes 31 of fiber termination box rightmost one by one, and optical fiber is then being pierced into light
When fine box, it is just less prone to the case where dislocation is perforated, the case where misdrawing hole is thus greatly reduced, also greatly improves and wear optical fiber
Efficiency；In addition, since each optical fiber perforation 11 just accommodates four optical fiber, glue is filled in optical fiber perforation 11 to cure in this way
When optical fiber, just do not have to so much glue, glue is made not flow out that section of light being attached to by sheath from optical fiber perforation
Fine surface and cause this section of optical fiber more fragile, therefore the more reasonable structure of the utility model helps to improve the use of 8 core fibres
Service life.
Although the utility model is described in detail with reference to above example, by the disclosure for people in the art
Member is not it is readily apparent that the case where departing from the principles of the present invention and scope that the claim limits
Under, the utility model can be made a variety of changes or be changed.Therefore, the detailed description of the embodiment of the present disclosure is only used for explaining, and
It is not intended to limit the utility model.
