Full name example
Optical cable OBR-ng(А)-HF-24Y (3x8) 400N
The cable consists of bundle of optical fibers in a buffer with aramid yarns layer. The cable sheath is flame retardant, halogen free, with low smoke and gas emission. Sheath of the cable for indoor installation is white. It is possible to produce any sheath color.
