Detail Information


The fibers, either of single-mode or multimode type, are positioned in a loose tube made of high modulus plastic. The tubes are filled with a water-resistant filling compound. A steel wire sometimes sheathed with polyethylene(PE) for cable with high fibre count, locates in the center of core as a metallic strength member. Tubes (and fillers) are stranded around the strength member into a compact and circular cable core. The PSP is longitudinally applied over the cable core, which is filled with the filling compound to protect it from water-ingress. Then, the cable is completed with a PE sheath.


☆.Accurate fiber excess length ensures good mechanical and temperature performance.
☆.High strength loose tube that is hydrolysis resistant and special tube filling compound ensure a critical protection of fibre. 
☆.Specially designed compact structure is good at preventiing loose tubes from shrinking.

☆.Crush resistance and flexibiity

☆. The following measures are taken to ensure the cable watertight:

1)Steel wire used as the central strength member

2) Loose tube filling compound

3) 100% cable core filling

4) PSP enhancing moisture-proof

☆.Fiber count: 12-144 cores.
