There are many RS232 interface devices such as terminals, printers, computers, video displays and ticketing machines that can be easily connected over the increasing use of Fibre links.
Often converters only offer 19.5kbps, 38.4kbps or up to 115.2kbps and operate as a DCE whereas the Metrodata FIMO-232 increases the asynchronous data rate up to the higher rate of 256kbps and has a cross over function supporting DCE to DTE, DCE to DCE and DTE to DTE configurations. The FIMO-232 is a standalone unit with one used at each end of the Fibre link
All Metrodata fiber modems are supplied as standard with SC connectors operating at a nominal wavelength of 1300nm. Other wavelengths are available on request, e.g. 850nm, 1550nm, 1550/1300 WDM. Other connectors are also available on request, e.g. ST, FC.
The FIMO-232 can easily be rackmounted in either a 1U two unit rackmount kit, or in a 6U eighteen unit rackmount kit .
