Name:Steel Tape layer Loose Tube Outdoor Cable GYTS       Model: GYTS

Steel Tape layer Loose Tube Outdoor Cable GYTS, 2~144 fibers central strength member (steel), jelly filled, fiber contained loose tube and PP filler (if necessary) stranded, water blocking jelly, longitudinally covered by copolymer steel tape, PE outer sheath. G652D SM fiber, detailed specification on your request.
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
◇ The armoring of corrugate steel tape make cable have nice properties of moisture resistance and crush resistance
◇ With small cable diameter, light cable weight, easily to lay
◇ 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 colour coded as per color coding scheme.
