Optical Communication Cable OKMT for Reliable Indoor and Outdoor Use

Cable for laying in plastic cable conduit, for laying on bridges and trestles, in cable trays, inside buildings and structures, in operation from minus 50 ° C to 60 °. The outer sheath is made of polymer compositions taking into account the application: when laying in a plastic pipeline - from polyethylene; when cable entry into the premises from polymer compositions that do not spread burning; power elements from aramid threads or glass roving 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.

Attenuation coefficient of multimode optical fibres (core/shell dimensions 50/125) at a wavelength of 850 nm not more than 3.0 dB/km, at a wavelength of 1300 nm not more than 0.7 dB/km. The attenuation coefficient...
