Description
Moxa’s OBU-102 fiber-optic bypass units add bypass relay
functionality to any network node. In linear topologies, a single power outage
or node failure can take out an entire chunk of the network, because
communications to all the network nodes further down the line are also cut.
With relay bypass, that node is bypassed in the event of a failure, and the
rest of the network is unaffected.
Bypass Relay Functionality
The OBU-102-SS-LC-FN sits between a node and the network to
add bypass relay functionality to any network switches that do not already support
this important function. In normal operations, the OBU-102 acts as a gateway
that forwards network traffic to and from the network switch. However, if power
is lost, the OBU-102 will bypass the unpowered switch and simply pass network
traffic to the next switch in the relay.
You can also find the OBU-102-SS-SC, OBU-102-SS-ST, and OBU-102-SS-LC
models in the Fiber Optic Adapters and Bypass Units.
