The access of the backup fiber will not affect the service line, but it will occupy 1 core of the backup fiber, which is suitable for scenarios with sufficient fiber resources.
The remote LSU light source continues to emit light, and the local OPD optical power detection board monitors the optical signal of the remote LSU light source in real time. When the optical signal intensity is lower than the FOPD alarm threshold, an alarm is reported, and the OMS system automatically controls the OTDR and OSW optical switches. The corresponding optical fiber line is tested
The OSW optical switch can also switch automatically, and the OTDR polls and tests the optical fiber line, and regularly monitors the performance of the optical fiber.
