The fibres, either of single-mode or multimode type, are positioned in a loose tube made of a 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 filing compound to protect it from water-ingress. Then, the cable is completed with a PE sheath.

Characteristics
1. Accurate fibre excess length ensures good mechanical and temperature performance
2. High strength loose tube that is hydrolysis resistant and special tube filling compound ensure a critical protection of fibre
3. Specially designed compact structure is good at preventing loose tubes from shrinking
4. Crush resistance and flexibility
5. The following measures are taken to ensure the cable watertight:
Steel wire used as the central strength member
Loose tube filing compound
100% cable core filling
PSP enhancing moisture-proof
