Optical cable with external symmetrical reinforcements

Abstract

The invention relates to an optical cable with external symmetrical reinforcements. The optical cable comprises an outer sheath and a cable core wrapped in the outer sheath. The periphery of the outer sheath is circular. The optical cable is characterized in that lugs protruding outwards are symmetrically arranged on two sides at the periphery of the outer sheath; the reinforcements are embedded in the lugs. The external parallel reinforcements protruding from the outer sheath are symmetrically arranged on two sides of the outer sheath to be used as tensile components, and compared with a conventional optical cable provided with reinforcements embedded in an outer sheath and having a circular section, the separation of the reinforcements from the optical cable can be facilitated, and stripping and laying of the optical cable are also facilitated; the thicknesses and the diameters of the optical cables of the same specifications are relatively reduced, so that materials are saved, the optical cable manufacturing cost is reduced, and the weight of the optical cable is reduced. The optical cable is suitable for direct bury and pipeline laying, has high self-supporting overhead laying performance, and after the reinforcements are separated from the optical cable, the optical cable has a high bending property and a high indoor laying property. The optical cable can be used for a backbone network and an access network, and is wide in application range.

Description

technical field [0001] The invention relates to an external symmetrical strength member optical cable used in the field of optical communication. Background technique [0002] The strength members on both sides of the existing symmetrical strength member optical cable are completely embedded in the outer sheath of the circular cross-section. This kind of strength member is embedded in the outer sheath layer. In order to ensure the quality of the outer sheath, the outer side of the strength member The distance from the outer edge of the outer sheath is generally not less than 1.0mm, and the minimum thickness of the outer sheath of the entire optical cable is generally not less than 2.0mm, which not only increases the weight of the optical cable and the cost of raw materials, but also makes it difficult to strip the optical cable. It is inconvenient to use. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an extern...
