Embodiment 1
[0033] This embodiment proposes a ring repeater system, including a near-end base station access control unit and several remote radio frequency remote coverage units.
[0034] The near-end base station access control unit such as Figure 6 as shown, Figure 6 It is a schematic diagram of a near-end base station access control unit, including a coupling antenna, a radio frequency processing subsystem, an FPGA subsystem, a serial-to-parallel conversion 8B10B decoder, a power supply subsystem, a monitoring subsystem, a clock subsystem, and at least one pair of optical transceiver modules , wherein the at least one pair of optical transceiver modules includes a downlink forward end and an uplink reverse end. Wherein, the letter D is used to indicate the downlink forward end, and the letter U is used to indicate the uplink reverse end.
[0035] The remote radio remote coverage unit such as Figure 7 as shown, Figure 7 It is a schematic diagram of a remote radio remote coverag...
Embodiment 2
[0052] The invention also proposes a network fault recovery method based on the ring repeater system. In this embodiment, the ring repeater system applied to the network fault repair method is the same as the ring repeater system proposed in Embodiment 1.
[0053] The network fault repair method based on the ring repeater system specifically includes:
[0054]Step S1: Receive the reported status of the ring link, and select a network fault repair measure according to the location where the ring link is disconnected, if it is the uplink reverse end of the last remote radio remote coverage unit and the near-end base station access control unit If the link between them is disconnected, execute step S2; otherwise, if the link is disconnected at another position in the ring link, execute step S3. The failure of the entire ring link is divided according to the location where the communication link is disconnected, which can include two situations. One is the connection between the ...
