Full name example

Optical cable OBV-ng(А)-HF-24Y (3x8) 400N

The cable consists of bundle of optical fibers in a buffer. The cable sheath is flame retardant, with low smoke and gas emission, does not emit corrosive and gaseous products during combustion and decay, with low toxicity of combustion gases. In the cable sheath, two fiberglass rods are diametrically laid, which prevent axial torsion of the cable and perform the functions of strength elements.
