Underground Fiber Optic Cables are used in various communication networks, designed for duct or direct burial installation, being a fully dielectric cable . Double Jacket cable is suitable for applications requiring the added mechanical and environmental protection.
Due to our new technology, the cables shows good flexibility and endurance to repeated bending, and great water blocking function.
This cable contains G.657A1 fibers made of high pure silica and germanium doped silica, protected by loose tubes filled with jelly.
