Reinforcement or enhanced non-metallic part.
By such scheme, described sheath is low-smoke halogen-free flame-retardant sheath.
By such scheme, described sheath cross-sectional width is 1.5 ~ 2.5mm, a length of 5 ~ 10mm.
By such scheme, each pair of described reinforcement equi-spaced apart, the spacer of every team two adjacent stiffeners is 1.3 ~
2.5mm。
By such scheme, in every pair of described reinforcement, the spacing between 2 reinforcements is 1.3 ~ 2.3mm.This practicality is new
Having the beneficial effects that of type: the 1st, in sheath interval laying 2 ~ 3 to reinforcement arranged in parallel up and down, the every pair of reinforcement is configured with 1 ~
The optical fiber of 4 cores so that leading in cable includes twin-core and multi-core fiber, can be classified as 2 ~ 3 at any time solely according to wiring requirements
Vertical butterfly-type leading in cable, and every separates independent optical cable and can continue a little to multiple spot according to its fiber number, makes introducing
Optical cable has and is easy to difference, the feature of multipoint connection, meets leading in cable by a little causing even the wiring needs of multiple spot at 2,
Especially in the optical-fiber network framework of a pair two, cloth wire routing is convenient, and work progress is simple, effectively increases cloth wire routing efficiency；
2nd, the side at sheath is correspondingly arranged point cable groove and stripping groove, and point cable and fiber can be made more convenient；3rd, arranging reinforcement makes to draw
The tensile property entering optical cable is strengthened so that it is possesses short distance and makes somebody a mere figurehead performance, is suitable for laying of various environment；4th, this practicality is new
Type simple in construction, it is easy to make, lay easy to use, is particularly suited for fiber entering household and the occasion of fiber to the desk uses.
