Optical line protection equipment 1+1
Description
Optical line protection equipment 1+1 is used in backup optical line protection system. The equipment uses advanced automatic optical line switching module, which is used in optical communication system for main or backup switching optical devices, it can automatically identify the status of the optical line signal is in main status or backup status, then it will switch optical line immediately to ensure when the main line broken, the backup line is still working, to improve the operator’s service quality.
