Optical Bypass Protection

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 node’s optical power or signal failure.


l Physical layer protection

l Transparent transmission

l Automatic switching with no interruption

l With LCD screen and control panel

l With network management

l To reduce all loss related to network node fault

l Real-time monitoring optical power of network node
