Full name example

Optical cable DOTa-P-48Y (6x8) 4kN

The cable consists of a loose tube core with a central strength element made of a dielectric rod with a spiral-twisted water blocking yarn around which optical loose tubes with freely laid fibers are twisted. The core is fastened with two winding threads with a water-blocking property. Aramid yarns and a MDPE sheath are laid on the core.
