Two-way transponding working method of optical fiber repeater and two-way transponding optical fiber repeater

Abstract

The invention relates to a two-way transponding working method of an optical fiber repeater achieved by a two-way transponding optical fiber repeater. The two-way transponding optical fiber repeater comprises a main transceiver, a plurality of transponding transceivers, a main antenna feeder system, a main comprehensive combiner, a transponding antenna feeder system, a transponding comprehensive combiner, a sending combiner, a receiving splitter, a receiving power divider and an emitting combiner, wherein the main transceiver has a plurality of different operating frequencies and operating modes. According to the two-way transponding working method of the optical fiber repeater, the optical fiber repeater can not only cover the weak field adjacent to a master block through the master block, but also cover the weak field adjacent to a slave block through the slave block and provide wireless relay transmission for a wireless communication system with the plurality of frequencies and modes, and wireless relay communication requirements of the optical fiber repeater system in areas of tunnels, basement and the like are satisfied.

Description

technical field [0001] The invention is a wireless communication relay transmission technology, which is suitable for relay transmission to a wireless communication system in a weak field section, and belongs to the technical field of wireless communication. Background technique [0002] In the current optical fiber repeater technology, the near-end unit and the far-end unit are usually used together. The near-end unit is close to the base station and sends and receives signals with the base station. Mutual transmission of signals, the remote machine is relatively far away from the base station and covers the weak field area near the remote machine, and the remote machine and the mobile station within the coverage of the remote machine send and receive signals to each other, realizing the cooperation between the near-end machine and the remote machine For the wireless relay transmission between the base station and the mobile station within the coverage of the remote station...

[0002] In the current optical fiber repeater technology, the near-end unit and the far-end unit are usually used together. The near-end unit is close to the base station and sends and receives signals with the base station. Mutual transmission of signals, the remote machine is relatively far away from the base station and covers the weak field area near the remote machine, and the remote machine and the mobile station within the coverage of the remote machine send and receive signals to each other, realizing the cooperation between the near-end machine and the remote machine For the wireless relay transmission between the base station and the mobile station within the coverage of the remote station, the near-end station does not have the function of covering the weak field area near the near-end station and sending and receiving signals with the mobile station, but in some such as In special areas such as tunnels and basements, due to special factors such as location and building boundaries, in these areas, the near-end unit must not only cooperate with the far-end unit to cover the far weak field area, but also need to monitor the weak field near the near-end unit. The field area is covered, that is to say, the near-end machine is required to not only transmit signals between the remote machine and the optical transmission system, and cooperate with the remote machine to cover the weak field area in the far area. The near-end machine also needs to cover the weak field near the near-end machine. area and has the function of sending and receiving signals with the mobile station. At the same time, the optical fiber repeater also needs to have a comprehensive transmission function, which can provide wireless relay transmission requirements for wireless communication systems with multiple frequency bands and multiple standards. Therefore, the existing optical fiber The repeater system cannot be applied to the wireless relay communication requirements in such areas
