4 Cores Composite Fiber Optic Cable 2.2mm Tube G657A2

Composite Fiber Optic Cable

Characteristics: 1.Low dispersion and attenuation. 2.LAP Aluminum belt is applied around the cable core, which is filled with the filling compound to protect it from water-ingress. 3.Proper design, precise control for fiber excess length and distinct stranding process render the excellent mechanical and enviromental properties. 4.The armoring of steel wire and corrugate steel tape make cable have nice properties of moisture resistance and crush resistance 5.Compact structure and lightness, flexible and good bend-resistant performance. Applicaiton: 1 Used for outdoor distribution box to the building's pipeline;overhead; buried. 2 Used in optical communication equipment room, light distribution frame light connection and optical 3 instruments, equipment connect to the light. 4 Used for tail fiber and jump in line. 5 Used for buildings surrounding into cable.
