Optical Bypass Protection System
OBP
Description
Optical Bypass Protection system (OBP) is a kind of intelligent optical switch system which can bypass fault node in optical transmission network to avoid breakdown of whole network communication. it can automatically switch by detecting the nodes optical power or signal failure.
t will take function by switching in default route to bypass the node and keep the transmission.
Features:
◆ Automatically instant switch
◆ Real-time monitoring nodes output power
◆ Reduce damage to network from nodes failure
◆ Improve reliability of transmission network and operators service quality
◆ Optionally switch between primary path and backup path without interruptting other nodes communication
