Digital optical fiber repeater is a kind of mobile communication base station signal pulling equipment, including near end unit and remote machine two equipment is through digital processing, digital optical transmission and software radio technology, etc., the base station RF part is pulled away, serving multiple cells of a new system solution. It effectively overcomes some technical defects and shortcomings of the original analog optical fiber repeater, and has increasingly become a necessary choice in the process of network construction and optimization.

It is widely used in blind areas and weak areas that are difficult to cover, such as shopping malls, hotels, airports, docks, stations, gymnasiums, entertainment halls, subways, tunnels, highways, islands and other places, to improve communication quality and solve the problem of dropped calls. It allows us to get a good experience on the signal.
