1overview 

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.

it will take function by switching in default route to bypass the node and keep the transmission.

 

u      system 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
