Abstract

The invention provides a photoelectric composite cable which comprises an outer sheath and a cable core arranged in the outer sheath. The cable core comprises an optical fiber bushing, copper conductors, a filler rope and cable paste, wherein the optical fiber bushing, the copper conductors and the filler rope are arranged in a spaced mode; the cable paste is filled among the optical fiber bushing, the copper conductors and the filler rope. A steel belt longitudinal wrap with which the outer circumferential face of the cable core is coated is arranged in the outer sheath, and reinforcers which extend in parallel with the cable core are arranged in the wall of the outer sheath. Compared with the structure that the reinforcers are arranged in the center of the cable core in the prior art, the photoelectric composite cable has the advantages that the reinforcers are arranged in the wall of the outer sheath, the radial dimension of the wall of the outer sheath is effectively utilized, space is not additionally occupied, the outer diameter of the cable core can be effectively reduced on the premise that tensile strength of the composite cable is guaranteed, and accordingly cost of the cable paste filled into the cable core can be lowered and the outer diameter dimension of the whole cable core can be reduced; the cable core is coated with the steel belt longitudinal wrap, so strength of the whole cable core can be effectively improved, and the cable core of the cable can be better protected.

Description

technical field [0001] The invention relates to a photoelectric composite cable. Background technique [0002] In recent years, with the rapid development of communication networks and people's demand for high-speed networks, mobile communications have evolved from analog to digital, from 2G to 4G, and from wireless voice services to wireless multimedia services, thus motivating operators to increase ARPU and develop The new frequency band supports the continuous growth of the number of users, more effective spectrum utilization and lower operating costs, so it has to undergo transformation and transformation. With the massive increase in network construction, higher requirements are put forward for compliant optical cables. [0003] Such as the photoelectric composite cable disclosed in the Chinese invention patent with the authorized announcement number CN201498256U, which includes an outer sheath and a cable core arranged in the outer sheath, and the cable core includ...
