Features
◇Low dispersion and attenuation
◇ Proper design, precise control for fiber excess length and distinct stranding process
    render the cable excellent mechanical and environmental properties
◇ With small cable diameter, light cable weight, easily to lay
◇ The armoring of corrugate steel tape make cable have nice properties of moisture resistance     and crush resistance
◇ Operating Temperature : -40~+60 ℃
Description
Loose tube style, optical fiber cable with metallic central strength member of steel wire/strand and moisture barrier inner sheathed. Cable protected by a black PE oversheath, suitable for duct or aerial application. Tubes contain optical single-mode or multimode fibers color coded as per color coding scheme.
