Abstract

The invention provides a photoelectric composite cable, which includes an outer sheath and a cable core arranged in the outer sheath. The cable core includes optical fiber sleeves arranged at intervals, copper wires, filling ropes, and filled in the optical fiber sleeves and copper wires. 1. Filling the cable paste between the ropes, the outer sheath is provided with a steel strip longitudinal wrapping on the outer peripheral surface of the cable core, and the outer sheath is provided with a wall parallel to the cable core. Extended reinforcement. Compared with the structure in which the strengthening member is arranged in the center of the cable core in the prior art, in the photoelectric composite cable provided by the present invention, the strengthening member is arranged in the sheath wall of the outer sheath, which effectively utilizes the diameter of the sheath wall. On the premise of ensuring the tensile strength of the composite cable, it can effectively reduce the outer diameter of the cable core, thereby reducing the cost of filling the cable core with cable paste and reducing the outer diameter of the entire cable. The steel tape longitudinal wrapping outside the cable core can effectively improve the strength of the entire cable core and better protect the cable core.

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 includes a...
