Converter serial interface – optical fibre
ODW-630-F2 is a fibre optic modem that converts between electrical RS-485 and a fibre
optical link.
ODW-630-F2 can also be used to convert from RS-232 to RS-485 by using a
ODW-620-F2 and ODW-630-F2.
Repeater – optical fibre links
ODW-630-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 electromag-
netic 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.
Data rate up to 1.5 Mbit/s
ODW-630-F2 converts data using rates from 300 bit/s up to 1.5 Mbit/s. Retiming
of the data ensures that the correct signal form is transmitted from the ODW-630-F2
converter.
