Optical fiber and copper wire hybrid cable production and manufacturing technology

Abstract

The invention discloses an optical fiber and copper wire hybrid cable production and manufacturing technology. A steel plastic composite tape is fixed on the internal wall of a PE sheath firstly, and two copper wires with insulating layers arranged along the radial direction of the steel plastic composite tape are fixed in the steel plastic composite tape; then a loose bushing of which the internal part is fully filled with optical fibers is arranged at one side of the two copper wires, and a steel wire with a sheath act as a supporting member to be arranged at the other side of the two copper wires; and finally water-resistant cable paste is filled in the gap of the internal part of the steel plastic composite tape so that the internal wall of the steel plastic composite tape is enabled to be completely supported and thus processing of an optical cable is completed. The steel plastic composite tape and the steel wire with the sheath act as the supporting structure of the PE sheath so that the optical fibers arranged in the loose bushing are ensured not to be damaged by wild animals or influenced by complex changes in weather under multi-protection of the PE sheath and the steel plastic composite tape, then stable working performance of the optical cable in rural areas can be guaranteed and thus an objective of reducing frequency of optical cable maintenance or replacement can be finally realized.

Description

technical field [0001] The invention relates to the field of optical cable manufacturing, in particular to a manufacturing process for hybrid cables of optical fibers and copper wires. Background technique [0002] In daily life, optical fibers are used for long-distance information transmission because the loss of light in optical fibers is much lower than that of electricity in wires. Most optical fibers must be covered by several layers of protective structures before use. The coated cable is called an optical cable. The protective layer and insulating layer on the outer layer of the optical fiber can prevent the surrounding environment from harming the optical fiber, such as water, fire, electric shock, etc. . [0003] The photoelectric hybrid cable is the cable twisted together by the optical cable box cable, that is, an insulated conductor is added to the optical cable structure, and the optical fiber and the power transmission copper wire are integrated. Since optica...

[0004] However, when laying communication base station cables in rural areas and remote areas of cities and towns, due to factors such as complex terrain, changing weather conditions, and numerous wild animals, the service life of photoelectric hybrid cables is greatly reduced, and signal or power interruptions often occur situation, and subject to the complex geographical environment, it is more difficult to maintain the line
