Pipe, so as to effectively by the size Control of whole optical cable in below 3.5mm, reduce the weight of optical cable, saved cost；
(2) reinforcement unit replaces aramid fiber or nonmetallic yarn from non-metal reinforcement member, and it is embedded into " Chinese character pin-shaped "
In low retraction high fire-retardance oversheath, so as to serve certain restriction effect to the retraction of oversheath, the temperature of optical cable is improved
Performance, in the environment of 85 DEG C/2H, the retraction of oversheath is less than 1%, can meet and be used in -40 DEG C -70 DEG C of environment；
(3) because FRP (fiberglass reinforced plastics) is embedded into oversheath in " Chinese character pin-shaped ", so as to enhance optical cable
Anti-tensile and lateral pressure resistant performance, it is ensured that optical cable is not in the situation of damage during construction and use, while also improving
The hardness of optical cable, when optical cable is laid in secret tunnel, without borrowing any auxiliary traction instrument, you can directly laid；
(4) there is stripping groove in surface of outer sheath and the symmetrical location aided rebroadcast of non-metal reinforcement member, make optical cable in work progress
In can easily tear, saved the engineering time, be additionally, since the high symmetry of its structure, this optical cable in laid processes,
Can with comprehensive carry out cable installation in pipe, it is to avoid the conventional optical cable with reinforcer is before being laid, it is necessary to first confirm it
The tedious steps in reinforcer orientation, substantially increase efficiency of construction；
(5) cable configuration described in the utility model is novel, simple, and cable size is small, lightweight, and intensity is big and easily applies
Work, is worthy of popularization.
