Abstract
An optical fiber status detection method includes: alternately sending, by a first station, an optical time domain reflectometer (OTDR) pulse and optical supervisory channel (OSC) data to a second station on a same channel, where the second station is a neighboring station of the first station; and receiving, by the first station, reflection light returned by the OTDR pulse by using an optical fiber between the first station and the second station, and obtaining an OTDR probe value according to the reflection light.
