When the first optical fiber 200 or the second optical fiber 300 fails, switching can be performed by the optical switch 100 to ensure normal operation of optical signal communication. The optical splitter 400 splits an optical signal input by the first optical fiber 200 or the second optical fiber 300 into two paths to be output, one path is transmitted to the ONU device, so that communication between the OLT and the ONU device is realized, the other path is transmitted to the photoelectric conversion module 500, the photoelectric conversion module 500 converts the optical signal into an electrical signal and inputs the electrical signal to the controller 600, the controller 600 can determine whether the communication is normal according to whether a data signal can be received, and then controls the state of the optical switch 100, and when a communication fault occurs, the optical switch 100 is controlled to operate and switch a line for transmitting the optical signal.
