Full name example

Optical cable TOS-P-16Y (1x16) 7kN

The cable consists of a single tube with freely laid fibers. The free space is filled with a hydrophobic gel in the optical single tubes. The single tube 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.
