Optical Communication Cable Type OKP for Reliable Connectivity

Cable for suspension on supports of communication lines, lighting, between buildings and constructions, inside buildings and constructions and operation at ambient temperature from minus 60 °? to 70 °?. The outer sheath is made of polymer compositions with consideration of application: at cable entry into the premises from polymer compositions that do not spread burning; in other cases - from polyethylene; power peripheral element made of wire or steel rope or fibreglass rod, optical modules twisted around the central power element.

Optical characteristics: Attenuation coefficient of single-mode optical fibres (core/shell dimensions 9/125) at 1310 nm wavelength not more than 0.36 dB/km, at 1550 nm wavelength not more than 0.22 dB/km.
