The fibers are positioned in loose tubers made of high modulus plastic. The tubes are filled with water-blocking compound. The steel wire, coated with polyethylene if necessary, locates in the center of core as the strength member. Tubes are stranded around the strength member to form the cable core. An aluminum laminated tape is applied around the caoble core, which is filled with the filling compound to protect from water ingress.A layer polyethylene is extruded as inner sheath. After the PSP is longitudinally applied over the inner sheath, the cable is complete with PE outer sheath.
Full selection water blocking construction, provide good performance of moisture-proof and water block;
Special filling gel filled loose tubes provide perfect optical fiber protection
Corrosion resistance phosphate steel wire with high modulus as central strength member
Longitudinal corrugated aluminum tape and steel tape gives desirable crush resistance.
Strict craft and raw material control enable lifespan over 30 years.
Application: long haul and building network communication;
Installation: direct buried;
Operating temperature: -40~+70℃;
Bending radius: static 10*D/ Dynamic25*D.
