Node Protection Bypass System

Part Number: FT-OBP-S

Node Protection Bypass System

Optical Bypass Protection System for Node Protection, Bi-directional protection in SMF, 1RU Rack Chassis

Node protection is a 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. Therefore to ensure that traffic from an LSP traversing a neighboring router can continue to reach its destination even if the neighboring router fails.
F-tone’s FT-OBP-S is a Standalone bypass protection equipment. In normal operations, the FT-OBP-S simply acts as a gateway that forwards network traffic to and from the network switch. However, if power is lost, the FT-OBP-S will bypass the unpowered switch and simply pass network traffic to the next switch in the relay. It is widely used in PDH, SDH, C/DWDM, power communication and CATV systems for optical monitoring.

Application Case

Protection Illustration


It shows an example of how you can implement node protection based on 1:1 protection operation. The 1:1 protection adopts 2x2 optical switch technologies. In default mode, the Tx signal towards the main line, through SDH/ADM node equipment, and the selector chooses the Rx traffic from the main line. When the middle node failure, the network will bypass the failured node and automatically switch to backup line.



It shows an example of how you can implement node protection based on 1+1 protection operation. In 1+1 operation, a splitter bridge sends the Tx signal to both line (the main line and the backup line) and a 2x1 selector switch selects the signal from one of the line. In default mode, traffic from the main line is selected. In this illustration, SDH/ADM act as an node between two transmission equipment. When the power failures, the selector near the Rx side of the failed traffic detects the failure, switches over, and selects the traffic from the backup line.
