The Metrodata FIMO-2100 is a standalone fibre optic extension unit for carrying synchronous serial data over resilient fibre. The FIMO-2100 supports data rates up to 8.192Mbps and is fully configurable in Nx64kbps steps. It also supports transparent oversampled operating modes.

This is an alternative product for the Probot 3006 X.21 and RS530 Serial Fibre Modem.

  • Resilient fibre uplink using SFPs
  • Multi-standard serial interface up to 8.192Mbps
  • Asynchronous or synchronous RS-232 up to 256kbps
  • RS-232, EIA-530, V.35, X.21, V.36, FM0 interface support
  • DTE or DCE interface via 25-way D-type connector
  • Data rate configurable in Nx64kbps steps
  • Must be used in pairs
  • Payload and protocol transparent
  • Minimal configuration of unit needed
  • Easy to install & maintain
  • Integral auto-sensing power supply (100-250V AC or -40V DC versions)
  • 12-24V DC power supply available on request
  • External alarm relay port
  • Compact modem style unit, built to European standards
  • Rack mounting kits for 2 or 18 units available
  • Quad option available with 4 units in a 1U box

The FIMO-2100 units are used in pairs across the resilient fibre link.

The FIMO-2100 serial interface is presented with both DCE and DTE ports, which each support multiple standards including RS-232 and EIA-530 directly, and V.35, X.21, V.36 and FM0 through the use of external adaptor cables. The user application determines whether the DCE or DTE port should be used on each unit, and this also affects the polarity of any cabling. Full details about application configurations and cabling options are available in the user manual.

The FIMO-2100 presents a DTE or DCE interface with the active interface type selected via a bit-switch. A cross-over function supports DCE to DTE, DCE to DCE or DTE to DTE formats.

The FIMO-2100 supports clock generation from 300bps to 38.4kbps for low speed RS-232 applications, and Nx64kbps from 64kbps up to 8.192Mbps for high speed applications (EIA530, X.21, V.36 and V.35). The RS232 interface will also operate at up to 256kbps when in clock pass through mode.

The maximum operating distance of the FIMO-2100 is dependant on the SFP transceiver used, with 5km supported as standard using multimode fibre, or up to 30km or 70km supported as standard using single mode fibre, although specific installations may only operate over lower distances due to the variations in losses of different types of fibre cable, the use of connecting fibre cables, or patch panels. When operating over 50% of the maximum distances it is advisable to calculate all fibre optic connector and cable losses and compare these with the fibre optic loss budget specified for this product.

The SFP fibre transceivers used with the FIMO-2100 have LC connectors at operate at a nominal wavelength of 1300nm. Other wavelengths are available on request, e.g. 850nm, 1550nm, 1550/1300 WDM and CWDM.

An array of LED indicators provide status and activity monitoring, and an alarm extension relay may be used to transmit Alarm conditions such as Fibre Optic Link Down.

The FIMO-2100 range can easily be rack-mounted in either a 1U two unit rack-mount kit or in a 6U eighteen unit rack-mount kit.

The FIMO-2100 is part of a range of products from Metrodata, offering fibre conversion solutions ranging from 300 baud RS-232, via Nx64kbps rates, through 2Mbps and up to 155Mbps for electrical to fibre conversion; or 155Mbps, 622Mbps or Gigabit Ethernet for fibre mode or wavelength conversion.
