Universal Fibre Optic Line Driver Transceivers

Use fibre instead of copper to send your RS-232/V.24, RS-422, and RS-485 data—without having to route it through protocol converters.
BLACK BOX® Universal Fibre Optic Line Driver Transceivers enable you to transmit and receive the signals over fibre optic cabling in both point-to-point or drop-and-repeat topologies. You can even mix protocols.
For instance, you can set one transceiver to interface with an RS-232/V.24 device at one end and another to interface with an RS-485 device at the opposite end. There's no need for a converter box at either end of the fibre link. The units perform all the necessary conversions!
