Optical Communication Cable OKZ Type for Installation in Various Environments

Cable for laying in cable ducts, tunnels, collectors, for laying on bridges and overpasses, inside buildings and structures, in soils of 1-3 groups, in operation from minus 50 ° C to 60 °. The outer sheath is made of polymer compositions with consideration of application: at cable entry into the premises from polymer compositions not spreading burning; in other cases - from polyethylene; power elements from aramid threads or glass roving or without them, power elements from 2 round steel wires or without them; inner sheath from polyethylene or without it; optical modules twisted around the central power element. Optical characteristics: Attenuation coefficient of single-mode optical fibres (core/shell dimensions 9/125) at wavelength 1310 nm not more than 0.36 dB/km, at wavelength 1550 nm not more than 0.22 dB/km.

The attenuation coefficient of multimode optical fibres (core/shell dimensions 50/125) at a wavelength of 850 nm is not more than 3.0 dB/km, at a wavelength of...
