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. The optical cable comprises an inner sheath and a plurality of optical fiber units arranged in the inner sheath, wherein each optical fiber unit comprises a loose tube and a plurality of optical fibers arranged in the loose tube, and further comprises an armor layer, a shield layer and an outer sheath orderly arranged outside the inner sheath from inside to outside. According to the optical cable disclosed by the invention, a steel-tape armoring and braided shield structure is adopted, an aviation steel wire rope central reinforcement in a twisting structure and a water-blocking rope manufactured by wrapping aramid fiber yarns by a water-blocking tape are adopted for a reinforcing structure, and each jacket is made of a wearable elastomer material, so that the flexibility, water-tightness and compression resistance and tension resistance of the high-reliability communication optical cable are improved, and the environment temperature of use and laying is wide in range.

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 ...
