NSN (Nokia Siemens Networks) fiber optic patch cable is a type of base station fiber optic cable, suitable for ordinary outdoor environment, often used in the roof of the tower, communication base station equipment port waterproof docking. The outer skin is low smoke-free, fire-resistant and waterproof to mice. There are ten sets of imported anti-pull aramids in the core.
Line softness is good, affected by the wiring space small, easy to put. The use of high-strength fatigue-resistant fiber to ensure the reliability and longevity of cables in a variety of harsh conditions of use. NSN fiber patch cord is with special coating layer and secondary composite structure, can absorb mechanical and environmental stress, fiber optic cable additional loss is small.

The small-cut fiber SZ stranding and aramid reinforced fiber single helix stranding, to ensure that the pull-far fiber cable has a large stretch strain window. Extremely high strength and light weight, strong weight ratio, round sheath compact, especially suitable for repeated storage.
NSN FTTA fiber optic cables are flame retardant high-strength, high-toughness polyurethane (PU) elastic body sheath, high oxygen index, good flame retardant, oil and chemical corrosion resistance, tear resistance, low gentle toughness good, strong elasticity, good stress buffer, wear-resistant pressure-resistant sheath. Tight sleeve cover color according to THE TIA-598-A standard chromatography, easy to cable distribution and end connection.
