Embodiment Construction

[0024] Such as figure 1 Shown is a schematic cross-sectional structure diagram of a preferred embodiment of the communication optical cable of the present invention. The communication optical cable includes an inner sheath 10 , a plurality of optical fiber units arranged in the inner sheath 10 , an armor layer 11 , a shielding layer 12 and an outer sheath 13 arranged outside the inner sheath 10 sequentially from inside to outside. The optical fiber unit includes a loose tube 3 and a plurality of optical fibers 1 arranged in the loose tube 3 . Preferably, fiber paste is filled between the optical fibers 1 in the loose tube 3 . The material of the inner sheath 10 and the outer sheath 13 is thermoplastic polyester elastomer (Thermoplastic polyester elastomer, TPEE). TPEE has the advantages of cold resistance, high temperature resistance, flexibility and wear resistance. The outer sheath 13 is covered on the outer surface of the shielding layer 12 by extrusion process. The arm...

Abstract

The invention discloses a high-reliability communication optical cable, comprising an inner sheath and a plurality of optical fiber units arranged in the inner sheath, the optical fiber units comprising a loose tube and a plurality of optical fiber units arranged in the loose tube The optical fiber also includes an armoring layer, a shielding layer and an outer sheathing which are sequentially arranged outside the inner sheath from the inside to the outside. The invention adopts steel tape armoring and braided shielding structure, meanwhile, the reinforcing structure adopts the central reinforcing member of the aviation steel wire rope of the stranded structure and the water blocking rope wrapped by the water blocking tape with the aramid wire, and each sheath layer adopts the wear-resistant elastic body The material improves the flexibility, water resistance and compressive and tensile strength of high-reliability communication optical cables, and has a wide range of ambient temperatures for use and laying.

Description

technical field [0001] The invention relates to the technical field of communication equipment, in particular to a high-reliability communication optical cable. Background technique [0002] With the development of optical communication and the rapid development of 3G and 4G networks, the scope and environment of communication optical cables are also different. Communication optical cables are usually used in various ways such as overhead or underwater. During the laying process, it is often stretched, wound, bent or squeezed. In addition, in areas where there are fewer people in our country, the temperature is lower or higher Areas, conventional optical cables are difficult to use, maintain and lay in long-term harsh environments, and the maintenance costs are very expensive. Therefore, communication optical cables are required to have good cold and high temperature resistance, flexibility, and water resistance. Excellent tensile strength and compressive strength, and can ...
