The basic structure and characteristics of leather fiber optic cable

Leather cable single-core, double-core structure is widely used, can also be made into a four-core structure, the cross section is 8, the reinforcement is located in the center of two circles, can use metal or non-metal structure, the fiber is located in the center of the 8-figure geometry. The fiber in the leather cable is G.657 fiber with a small bending radius. The 200mm bending radius is suitable for laying pipelines or open wires in buildings. The unique 8-figure structure of the leather cable can realize the field terminal in the shortest time, and the various field connectors manufactured by Corning, 3M, Fujikura Company can be used with 2.0mm×3.1mm leather cable for standard size, and are widely used around the world.

According to the type of reinforcement, leather cable can be divided into metal reinforcement and non-metal reinforcement. Metal reinforced leather cable cable can achieve greater tensile strength, suitable for long-distance indoor horizontal wiring or short distance indoor vertical wiring. The leather cable cable of the metal reinforcement is not strengthened with the traditional phosphating steel wire, but with a special copper clad steel wire material, which can avoid the damage of the phosphating steel wire in the construction of the project and the winding of the cable. Non-metal reinforced leather cable using FRP as a strengthening material, can achieve all non-metal household, has excellent lightning protection performance, suitable for indoor introduction.

The outer sheath of the Optical Cable is generally made of PVC material or LSZH material, the flame retardant of LSZH material is higher than that of PVC material, at the same time, black, LSZH material can prevent ultraviolet erosion, prevent cracking, suitable for outdoor introduction indoors.
