Abstract
This application discloses an optical signal transceiver apparatus, and belongs to the communications field. The apparatus includes: an optical signal generation module, configured to generate a to-be-sent optical signal and a local oscillator optical signal, where the to-be-sent optical signal includes an OTDR signal; an optical combining/splitting module, configured to: receive a to-be-processed optical signal from an optical fiber; and input the to-be-processed optical signal into an coherent receiving module; the coherent receiving module, configured to coherently receive the local oscillator optical signal and the to-be-processed optical signal to obtain a to-be-processed electrical signal; a signal processing module, 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.
