MOXA

Optical Fiber Bypass Units

Moxa’s fiber bypass units add bypass relay functionality to any network node, whether it is in a linear or collapsed ring topology. When a power outage occurs, the optical fiber bypass units bypass the inactive switch, which allows the network to keep functioning normally.
