Unitube Light-armored Optical Fiber Cable (GYXS/GYXTW)

Optical Fiber Cable 1 hydrolysis-resistant high strength tube 2.special tube filling compound 3.PSP enhancing mostiture-proof Fiber Optic Cable Unitube Light-armored Cable (GYXS/GYXTW) Description The fibers, 250µm, are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. The tube is wrapped with a layer of PSP longitudinally. Between the PSP and the loose tube water-blocking material is applied to keep the cable compact and watertight. Two parallel steel wires are placed at the two sides of the steel tape. The cable is completed with a polyethylene (PE) sheath. Characteristics 1.Good mechanincal and temperature performance 2. High strength loose tube that is hydrolysis resistant 3.Special tube filling compound ensures a critical protection of fiber 4.Crush resistance and flexibility 5.PSP enhancing mostiture-proof ability 6.Two parrallel steel wires enure tensile strength 7.Small diameter,light weight and friendly installation
