Full name example

Optical cable DOL-P-48Y (6x8) 2,7kN

The cable consists of a loose tube core with a central strength element made of a dielectric rod 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 corrugated steel tape armor and a flame redundant while single installation sheath.
