Abstract

The invention discloses a photoelectric composite cable, and further relates to application of the photoelectric composite cable in a 5G front-haul network. The photoelectric composite cable comprisesa central reinforcer, an optical signal layer coating the central reinforcer, a photoelectric hybrid layer coating the optical signal layer, and an electric signal layer coating the photoelectric hybrid layer, wherein the optical signal layer is provided with a plurality of optical units; the photoelectric hybrid layer is provided with a plurality of electric units and a plurality of optical units, and the electric units and the optical units are alternately arranged; the electric signal layer is provided with a plurality of electric units; and each optical unit is provided with four opticalfibers, and each electric unit is provided with a cell. According to the photoelectric composite cable, a cable is processed by adopting a mode of combining the optical units and the electric units, so that the photoelectric composite cable is compact in structure, small in occupied space, easy to construct, low in comprehensive cost and convenient to lay and use; the photoelectric composite cableis applied to the 5G front-haul network, communication and power supply problems of multiple devices can be solved from BBU and RRU ends of a base station by only one cable, and the comprehensive cost of laying of drop cables of the base station is reduced.

Description

technical field [0001] The invention relates to the technical field of photoelectric composite cables, in particular to a photoelectric composite cable, and also to an application of the photoelectric composite cable in a 5G fronthaul network. Background technique [0002] Since the concept of cellular communication was proposed in the 1970s, mobile communication has experienced four generations of development, and the fifth generation mobile communication system (5G) is moving towards higher speed, lower delay, and lower power consumption. direction. The 5G wireless access network will adopt the C-RAN architecture, that is, the BBU (baseband processing unit) of the base station will be centralized, and the RRU (remote radio frequency module) will be spread far away through the front transmission, and distributed in the streets and alleys, mountain villages and fields. This means that a large number of optical-electrical hybrid cables need to be laid between the BBU pool an...
