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.

Abstract: A data verification method and apparatus, a device, and a storage medium are disclosed, and related to the field of data storage technologies. The verification method includes: during data verification, first verification information is obtained, according to a target algorithm, based on verification information of data, second verification information is obtained, according to the target algorithm, based on a target verification set determined based on a first verification set and a second verification set, and then the first verification information is compared with the second verification information, to obtain a verification result. The verification method can support a plurality of types of data operations, and improve a degree of parallel data processing while ensuring security and accuracy of data verification, thereby improving data processing efficiency.
