In fiber optic networks, an optical bypass helps in this situation.
If a predefined voltage is undershot, or in the event of a complete power failure, or if a signaling line changes state, the optical signal is redirected from the incoming fiber optic line to the outgoing fiber optic line within a few milliseconds.
This bypasses the node, that is out of service.
Once operating conditions are restored, the network node is reintegrated into the line without operator intervention.
To prevent the connection from being interrupted during the restart of the affected component, the termination of the bypass can be delayed by up to 75 seconds.
The system not only provides protection against interruption of data transmission via the fiber optic lines due to defects or power outages in data nodes, but also allows for decommissioning for maintenance or conversion purposes without interrupting the line.
Even a redundant ring can fail if maintenance work on one node is followed by a failure on another node, or if several network nodes are affected by special weather events.
Since the bridging is protocol-neutral, it can be used for both Ethernet lines and all fieldbus systems with an optical line structure.
