Transition xFMFF

Optical Line Converter offers protocol transparent connectivity between fiber optical links with an added flexibility of Small Form Factor Pluggable (SFP) technology. xFMFF4040-100 is a universal platform to accommodate any optical conversion options available via SFP interfaces.

These converters offer an excellent upgrade path for the networks. Today's Fast Ethernet applications can be upgraded to Gigabit speeds tomorrow with a simple SFP swap. The converter remains installed, managed and fully operational at any of these speeds.

Two SFP module slots allow for seamless connectivity between different wavelengths or fiber modes for speeds up to 2.5Gbps. Protocol independence allows for use in broad range of applications including Fast and Gigabit Ethernet, FDDI, ESCON, SONET OC-3, OC-12, OC-48 and Fibre Channel.


  • Two SFP Slots for SFP interfaces
  • CWDM and DWDM SFP-ready platform
  • Link Pass Through
    Link Pass Through is a troubleshooting feature that allows the media converter to monitor both the fiber and copper RX ports for loss of signal.
  • Protocol Transparency
  • Automatic Link Restoration
    Transition Networks's converters will automatically re-establish link in all network conditions.
