摘要
A method for detecting a submarine optical cable line includes: splitting a detection signal input to a first optical functional unit in an optical functional module of an optical cable line into a first detection signal and a second detection signal; directly coupling and looping back the first detection signal to an output end of a second optical functional unit in a direction opposite to the first optical functional unit to constitute a first loopback path, and outputting a first detection loopback signal; looping back the second detection signal passing through the first optical functional unit to the output end of the second optical functional unit to constitute a second loopback path, and outputting a second detection loopback signal; and detecting a status of the submarine optical cable line according to power of the first detection loopback signal and power of the second detection loopback signal.
