PM485FIBRE - RS232/RS485 to Fibre Module

The PMFibre Optic converter unit is a bi-direction fibre optic unit used to convert 2-wire RS485 twisted pair (or 3 wire RS232) data communications signals for transmission over multi-mode fibre optic cables.

The converters can be used to extend the limited distance capabilities of RS485 devices for up to two kilometres. The PMFibre Optic converter is ideal for extending RS485 signals through areas of high electrical noise due to the EMI immunity of fibre. 

The unit is also ideal for isolating Promux modules housed in an electrical panel from long RS485 networks which could suffer from ground loop problems. 

The unit is fully configurable via DIP switches for baud rate, parity, data bits and stop bits. The isolation also prevents ground loops between different parts of the network.
