Full name example
Optical cable DPOm-P-32Y (4x8) 6kN
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. A suspension element is a steel rope. MDPE sheath is laid on the core and on the suspension element.
