Intersection Surveillance Node Optical Line Protector FW-OLPB
The source describes highway monitoring nodes every2km in a chain: an intermediate power failure disconnects downstream nodes, preventing evidence retrieval after incidents. It cites an above98% highway/public-security monitoring uptime requirement. FIBERWDM 瑞东科技's FW-OLPB automatically detects protected-node power and instantly bypasses failed nodes optically, maintaining connectivity. It suits highway/tunnel surveillance and improves downstream equipment availability. In a single-fiber A–C–B chain, C failure interrupts downstream communication. Adding OLPB bypasses C. The stated normal path is A equipment → A interface (protection module) → L interface (C equipment) → R (protection module) → B interface (protection module) → B equipment. On C power loss, the path becomes A equipment → A interface → B interface → B equipment. Optical switching automatically changes the default path and carries traffic during power interruption, preserving A–B communication. Restored C power automatically returns normal A–C–B operation. Diagram references in the cached description illustrate these states.
