Description

technical field

[0001] The invention relates to wire and cable technology, in particular to a lightning protection optical cable capable of lightning protection and transmission of optical signals and electric power. Background technique

[0002] Based on the base station construction sites are mostly open, highland or mountainous area, the terrain is complex and the working environment is harsh, the equipment of the base station is easily damaged by lightning weather, the outdoor cables of the base station, especially in the northern area where the temperature is low in winter and directly exposed to ultraviolet rays, are prone to damage. Aging and damage will affect the work of the base station. The cable used as a communication base station should have certain shielding and anti-interference performance to ensure that its own electromagnetic field does not interfere with other signals and is not interfered by the external electromagnetic field on the cable core.
