The fibers, are positioned in a loose tube made of a high modulus plastic. The tube is filled with a water-resistant filling compound. The tube is wrapped with one layer of coated steel tape longitudinally. Two paralleled steel wires are placed at the two sides of the steel tape. Outside the tube and strength members, the polyethylene sheath is extruded to provide the UV resistance
Full section water blocking construction, provide good performance of moisture-proof and water block;
Special filling gel filled loose tubes provide perfect optical fiber protection.
Two parallel steel wires provide desirable tensile strength and crush resistance.
Suitable for access network (especial in FTTC and FTTB) interoffice connection and CATV network
Strict craft and raw material control enable lifespan over 30 years.
Application: long haul and building network communication;
Operating temperature: -40~+70℃;
Bending radius: static 10*D/ Dynamic20*D.
