Provided are an optical transceiving device and method. This device includes: an OTDR transmitter, an OTDR receiver, an input optical interface, an output optical interface, a housing, a splitter, and a sideband filter, and by means of a technical scheme of the present disclosure, this device has a function of sending and receiving OTDR detection optical signals, supports a function of wave multiplexing/de-multiplexing of detection optical signals and service optical signals, guarantees that transmission of the service optical signals and the detection optical signals on a main optical path do not influence each other, and may be taken as an important part of an optical module and be integrated into an optical transmission system device, enables an OTDR detection function to be set inside a system, and reduces an operation and maintenance cost of optical fibre failure detection. |
