The fibers, 125μ M, 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 of GYXTW:

1. High quality optical fiber provides good transmission performance
2. Accurate fiber excess length control ensures excellence mechanical and temperature performance
3. Strict craft and raw material control for cable stably operating over 30 years
4. Special filling gel filled loose tubes provides optical fiber protection
