APC Optical Line Protection Switch DWDM Equipment Automatically
OLP System with Real-time Fiber Power Monitoring and automatic Switching
Optical Line Protection Equipment (OLP) is a kind of equipment used in the field of optical fiber communication to switch between the main and standby optical paths. It can automatically identify the optical signal status of the main and standby optical fibers, and perform instantaneous switching of the optical paths. Prevent the normal operation of communication when the main optical cable has a full-blocking obstacle. The optical path protection equipment mainly has the functions of real-time monitoring of optical power, optical path switching, and alarms. The port that establishes the route is transparent to the speed and interface, and its switching route is established in the optical domain.
