Optical Communication Cable Type VD for Reliable Fiber Connections

Cable for the manufacture of connecting optical cords, for stationary installation of equipment, as well as for use in local computer networks as optical cords and for the formation of horizontal SCS with laying in boxes to the working inside buildings and structures and operation at ambient temperatures from minus 10 ° C to 50 ° C. Two parallel optical fibres, each in an individual dense buffer coating, reinforcing strands, enclosed in their sheaths made of a composition that does not spread combustion in group laying. The two sheaths are connected by a jumper Optical characteristics: The attenuation coefficient of single-mode optical fibres (core/sheath dimensions 9/125) at a wavelength of 1310 nm is not more than 0.36 dB/km, at a wavelength of 1550 nm not more than 0.22 dB/km.

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