摘要： This application discloses an optical signal transceiver apparatus, and belongs to the communications field. The apparatus includes an optical signal generation module, an optical combining/splitting module, a coherent receiving module, and a signal processing module. The optical signal generation module is configured to generate a to-be-sent optical signal and a local oscillator optical signal, where the to-be-sent optical signal includes a first optical time domain reflectometer OTDR signal. The optical combining/splitting module is configured to: receive a to-be-processed optical signal from an optical fiber; and input the to-be-processed optical signal into the coherent receiving module. The coherent receiving module is configured to coherently receive the local oscillator optical signal and the to-be-processed optical signal to obtain a to-be-processed electrical signal. The signal processing module is configured to: obtain a first digital signal and a second digital signal from the to-be-processed electrical signal based on a signal frequency; process the first digital signal to obtain a communications code stream; and process the second digital signal to obtain information used to reflect a feature of the optical fiber. This application expands a dynamic range of OTDR signal detection.
