2.Filler protect loose tuber fiber
4.The waterproof performance of optical cable is ensured by using waterproof material to prevent the longitudinal seepage of optical cable.
5.Optical fiber has large transmission capacity, less loss, long transmission distance, small size, light weight, low dispersion and easy laying.
6.Two parallel wires ensure the tensile strength of the cable, and the suitable temperature of the cable is -40 to +70 ℃
