Composition), it not only ensure that the tensile resistance of Integral-type optical cable main body, and ensure that whole cable is torn by third tearing groove
Independent stranding can also have higher tensile resistance after branch；
The structure of (3) first, second, third tearing grooves so that fiber cable branch is simple, easy to operate, uses third tearing groove
When easily can tear into two individual butterfly sub-lights from centre by Integral-type optical cable in the case of without using tool very
Cable；Optical fiber can be easily put by when using first, second tearing groove and fiber optic bundle is stripped out, all very saved
Power, convenient for constructing operation；
(4) containing several optical fiber and the flexible aramid fiber enhancement layer of filling, (fiber optic bundle outer diameter is 0.85- in fiber optic bundle
0.95mm, preferably 0.9mm), fiber optic bundle is not only provided with certain tensile resistance, but also in high and low temperature alternative environment next time
It contracts minimum, so as to not influence the optical transmission performance of internal optical fiber；
This special structure design had both reduced the external dimensions of optical cable, at the same also improve optical cable performance and optical fiber it is close
Intensity requirement, allows optical cable to be more easily used in the occasion of the special installations environment such as computer room, house service case.
