Product Description
Low dispersion and attenuation
Proper design, precise control for fiber excess length and distinct stranding process render the cable excellent mechanical and
environmental properties
The armoring of corrugate steel tape make cable have nice properties of moisture resistance and crush resistance
Operating Temperature : -40~+60 ºC
