The Fiber Optic switch is used for designing an Ethernet network in loop topology. On account of the loop structure, the network is fully redundant since, in the case of an fiber rupture, it is possible to still communicate through the other side of the loop. In addition, every Fiber Optic switch has two operating voltage inputs (24 V DC) and one relay for the forwarding of fault signals.
