The Metrodata FIMO-2000 is a standalone fiber optic extension unit for carrying synchronous serial data. The FIMO-2000 supports data rates up to 4.096Mbps and is fully configurable in Nx64 Kbps steps.

The FIMO-2000 presents a DTE or DCE interface with the active interface selected by setting a bit-switch. A cross-over function supports DCE to DTE, DCE to DCE or DTE to DTE formats.

Rear: FIMO2000 - Serial to Fiber Optic Modem

The FIMO-2000 units are used in pairs across the fiber link.

The serial interface supports multiple standards including RS-232 and EIA-530. With the use of external adaptor cables, V.35, V.36 and X.21 are supported.

When used with single mode long haul transceivers the FIMO-2000 can extend up to 70kms. An array of LED indicators provide status and activity monitoring, and an alarm extension relay may be used to transmit Alarm conditions such as Fiber Optic Link Down.

All Metrodata fiber converters 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 FIMO2000 range can easily be rackmounted in either a 1U two unit rackmount kit or in a 6U eighteen unit rackmount kit .
