产品描述
1.1 General Design（Outdoor fiber optic cable）
OpticalFiber is constructed of a germanium doped silica based core with a pure silicacladding which meets ITU-T G.652 standard. Two layers of UV curable acrylateprotective coating are applied over the cladding to provide maximum fiberlifetime.

2. Fiber Optic Cable
2.1 GeneralDesign
The colorcoded fibers are housed in multiple color coded plastic loose tubes which arestranded around a central strength member utilizing Reverse Oscillating Lay(ROL).
Waterblocking yarn and water-blocking tape, filling the interstices within the core,provides protection against water ingress.MDPE sheath with 2 rip cords iscovered over the cable core.
