Converter serial interface – optical fibre
ODW-620-F2 is a fibre optic modem that converts between electrical RS-232 and a fibre
optical link.
ODW-620-F2 can also be used to convert from RS-232 to RS-485 by using a
ODW-620-F2 in the same link as ODW-630-F2.
Repeater – optical fibre links
ODW-620-F2 is a fibre optic repeater that repeats received data from one fibre link
out to the other link. This is useful e.g. for long distance communication, where electro-
magnetic interference may occur or when isolation of the electrical network is needed.
The maximum optical fibre distance depends on selected fibre transceiver and fibre type.
