Problems solved by technology

[0002] In the current wireless system, there are many kinds of wireless communication systems, such as GSM, WCDMA, TD-SCDAM, CDMA2000, intercom private network and other wireless communication systems. In the existing technology, the above wireless communication systems have their own The dedicated optical fiber repeater is used as a relay device, but in some special areas and tunnels, due to the inconsistency of the network planning of each wireless communication system, the location of the base station of each system, the limitation of the number of optical fibers, the number of links of the optical fiber repeater, and the optical transmission route Influenced by factors such as inconsistent length and user distribution, mutual interference, and isolation requirements between systems, in these areas, all relay equipment cannot be installed in them to meet the relay requirements of various wireless communication systems. Therefore, the existing The optical fiber repeater cannot meet the relay communication requirements of each wireless communication system user in this type of area
