Full name example

Optical cable DPS-P-48Y (6x8) 10kN

The cable consists of a loose tube core with a central strength element made of a dielectric around which optical loose tubes with freely laid fibers are twisted. The free space is filled with a hydrophobic gel in the optical loose tubes and in the core. The core is covered with intermediate PE sheath. The intermediate PE sheath is spirally covered with the steel wire armor. The free space is filled with a hydrophobic gel between wires. The armor is covered with HDPE sheath.
