Abstract

The invention relates to the technical field of photoelectric composite cable, in particular to a photoelectric composite cable for 5G antenna, which comprises a copper conductor and an optical fibercore, wherein the number of the copper conductors is two, the outer side of each copper conductor is coated with an insulating layer, and a conductive cable is formed; a plurality of optical fiber cores are provided, and the plurality of optical fiber cores are wrapped in an optical fiber loose sleeve, and a gap between the inner wall of the optical fiber loose sleeve and the outer wall of the optical fiber core is filled with an optical fiber water blocking paste layerto form a signal cable; Two conductive cables and one signal cable are stranded together, and a non-hygroscopic heat insulation wrapping tape is wrapped on the outer side thereof, and a wired core paste layer is filled between the inner wall of the non-hygroscopic heat insulation wrapping tape and the outer wall of the cable; the outer wall of the non-hygroscopic heat insulation wrapping tape is bonded with a metal moisture-proof layer, and the outer side of the metal moisture-proof layer is provided with a protective layer. The invention has the advantages that the composite cable can simultaneously satisfy the power supply and the signal transmission of the antenna, the one-time construction meets the two functional requirements, the engineering cost is lower, the system is simpler, and the maintenance is more convenient.

Description

technical field [0001] The invention relates to the technical field of photoelectric composite cables, in particular to a photoelectric composite cable for 5G antennas. Background technique [0002] In the era of integrated base stations, the antenna and the computer room are connected by a feeder RF cable, and the antenna is also passive. [0003] In the 5G era, with the separation of the BBU (Baseband Processing Unit) and the RRU (Remote Radio Unit), and the integration of the RRH (Remote Radio Head) with the antenna, the antenna has changed from a passive source to a time source. The active antenna integrates the radio frequency into the antenna tightly, without the loss of the feeder line, while ensuring the same output power, the power consumption is smaller. The radio frequency part of the base station is placed on the tower for natural heat dissipation, which can greatly reduce the use of air conditioners in the computer room , which effectively reduces the energy co...

Problems solved by technology

[0005] The existing optical fiber cable connecting BBU and RRU can only transmit optical signal and cannot supply power, so it is not necessary to install another pair of conductive cables to connect BBU and RSU to provide DC48V power supply for the antenna

Antenna photoelectric separation connection, the system is more cumbersome, the construction workload is heavy, and the project cost is higher
