Optical Fibre Cableof OKSNMt typePART IFUNCTIONThe cable is designed for hanging on supports of communication lines,railway contact systems, city illumination poles with a remote element.1DESIGN1. Peripheral strength member – steel rope2. Modules with optical fibres3. Hydrophobic filling in modules and between modules and sheath4. Optical fibres produced by Fujikura, Corning, Draka5. Central strength member – fibreglass plastic rod6. Jacket from polyethyleneSERVICE AND ASSEMBLY CONDITIONS1. Operating temperature range – from -60°C to 70°C2. The cables are designed for mechanized and manual installation at atemperature not lower than -10°C3. Admissible bending radius during assembly not less than 20 nominalcable diameters during operation and not less than 250 mm duringinstallation and assembly4. The cables’ service life, not less than – 25 years5. The cables are resistant to mold fungi, dew, rain, frost, salt fog, solarradiationSPECIFICATION1.
