Mobile base station ratproof radio-frequency remote optical fiber cable capable of conducting thunder and lightning

Abstract

The invention relates to communication optical fiber cable techniques, and in particular relates to a mobile base station ratproof radio-frquency remote optical fiber cable capable of conducting thunder and lightning. The optical fiber cable comprises a cable core and an outer protecting sleeve, wherein the cable core consists of a tight sleeve layer, a subunit reinforcing component and a subunit sheath which are wrapped outside optical fibers in sequence; a plurality of cable cores are twisted with reinforcing pieces and are wrapped with an inner sheath; the inner sheath is sequentially wrapped with a steel strip and the outer protecting sleeve; adhesion force of the steel strip and the outer protecting sleeve can meet a torsion experiment that the optical fiber cable is twisted for 180 degrees for 10 times forward and backward. Due to adoption of an optical-fiber tight sleeve structure, the outer protecting sleeve as an outer protecting layer, and novel structural design and process control, not only is ordinary wireless radio-frequency remote optical fiber cable property ensured for the optical fiber cable, but also the conduction function is enhanced, the thunder and lightning conduction is improved, the ratproof property is improved, and the rapidness and the convenience in construction are achieved by using the special process steel strip after an uncoated layer is peeled off, so that the construction period and the construction cost are greatly reduced.

Description

technical field [0001] The invention relates to communication optical cable technology, in particular to a lightning-guiding mobile base station anti-rat radio frequency remote optical cable. Background technique [0002] With the progress of society, mobile communication develops rapidly and spreads to every corner of the country. Whether mobile communication base stations can operate normally is the key to mobile communication. Most of the mobile base stations are built in the geographical position with wide view or higher terrain, higher hillsides, mountains, and lightning activities are extremely frequent. It is very important to carry out lightning protection work for mobile communication base stations. Due to frequent lightning activities, it is very important for the safe operation of base station equipment. pose a great potential threat. The lightning protection of the base station is a systematic and complex project. The base station is mainly composed of communica...

Problems solved by technology

However, it is not enough to protect the relevant ports of the RRU. It is also necessary to protect the ground network of the base station, the equipotential connection in the station, the protection of the incoming power cable and the transmission optical cable, the lightning overvoltage protection of the power supply system in the station, and environmental monitoring. System protection and other aspects, comprehensive protection can achieve good protection effect
