Full name example
Optical cable TOL-P-24Y (1x24) 2.7kN
The cable consists of a single tube core 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 corrugated steel tape armor and a flame redundant while single installation sheath. Two fiberglass rods are diametrically laid, which perform the functions of strength elements.
