Weather-proof indoor and outdoor center sleeve type non-metal optical cable

Abstract

The invention relates to the technical field of building above the ground, pipe laying and home-entry communication optical cable manufacturing, in particular to a weather-proof indoor and outdoor center sleeve type non-metal optical cable. The optical cable comprises optical fibers or fiber optics bundles, the outsides of the optical fibers or the fiber optics bundles are wrapped by fillings and a sheath, the optical fibers or the fiber optics bundles are placed in a sleeve after coloring, the space between the optical fibers or the fiber optics bundles and the sleeve is filled with fiber paste, the outside of the sleeve is wrapped by a non-metal reinforcement part, and a water-stopping object is arranged in the non-metal reinforcement part. The outside of the non-metal reinforcement part is wrapped by the sheath, and non-metal enhancement rods are arranged in the sheath. The center sleeve type structure is adopted, and the non-metal reinforcement part and the non-metal enhancement rods are arranged in the optical cable, so that the outer diameter of the optical cable can be reduced, and existing pipeline resources are sufficiently utilized; the optical cable is light in weight, convenient to construct and free of grounding processing and is made of non-metal material, and construction cost can be reduced; the non-metal reinforcement part does not need to be imported, and the non-metal enhancement rods are additionally arranged in the sheath layer to improve the stability of product quality.

Description

technical field [0001] The invention relates to the technical field of overhead and pipeline laying and household communication optical cable manufacturing, in particular to a weather-resistant non-metallic central tube type indoor and outdoor optical cable. Background technique [0002] At present, there are mainly two types of outdoor central tube optical cables: GYXTW and GYFXTY. The GYXTW type optical cable uses steel strips and steel wires as reinforcements. The outer diameter is thick and the weight of the optical cable is heavy. At the same time, it is made of metal and needs to be grounded. The labor cost during construction is relatively high. The safety performance indicators of this optical cable with metal materials are compared with non- It is worse than metal fiber optic cable. GYFXTY type non-metallic bundle tube optical cable uses aramid yarn as the reinforcement, and the cost is relatively high. In addition, because there is no material with high hardness i...

Problems solved by technology

GYXTW type optical cable uses steel belt and steel wire as reinforcement, the outer diameter is thick, the weight of the optical cable is heavy, and it is made of metal, so it needs to be grounded, and the labor cost is relatively high during construction. Worse than metal fiber optic cables

GYFXTY type non-metallic bundle tube optical cable uses aramid yarn as a strengthening member, and the cost is relatively high. In addition, because there is no material with high hardness in this structure, the material shrinkage of the optical cable sheath directly affects the attenuation index of the optical fiber in the optical cable, and the qualified rate of the optical cable Relatively low, the outer diameter of the optical cable is relatively thick, occupying a lot of pipeline resources
