PLANET MFB-FX SFP Transceiver

The PLANET MFB-FX is a Small Form-factor Pluggable transceiver designed for 100Base-FX Fast Ethernet links over multi-mode fibre. It targets network engineers and system integrators who need a standards-compliant module to connect switches, routers or media converters across campus or building backbones.

100Base-FX over multi-mode fibre

The module operates at a 1310 nm wavelength and supports link distances up to 2 km on multi-mode cable with LC duplex connectors. It delivers a 125 Mbps signalling rate compliant with IEEE 802.3u and FDDI ISO/IEC 9314-1, so it handles typical Fast Ethernet backbone traffic but will not serve Gigabit or 10 Gigabit segments.

SFP MSA compliance and industrial temperature

The transceiver follows the SFP Multi-Source Agreement for mechanical and electrical interchangeability and includes serial ID functionality for host-system recognition. It is rated for an operating temperature range of 0 to 60 degree Celsius and meets Class 1 laser safety per IEC 825, making it suitable for standard indoor network equipment racks.

Questions about this item

Will this 100Base-FX transceiver link with my older 100 Mbps switches that use LC multi-mode fibre?

Yes, it complies with IEEE 802.3u 100Base-FX and FDDI ISO/IEC 9314-1, so it interoperates with legacy 100 Mbps LC multi-mode equipment.

How can I verify the module is recognised and healthy after I insert it?

The transceiver supports Serial ID functionality; your switch or router will read the identifier and report link status at 125 Mbps over the 1310 nm multi-mode connection.

Does the box include the LC patch cables I need for a 2 km run, or must I buy them separately?

Only the SFP transceiver is supplied; LC multi-mode patch cables for the 2 km distance must be purchased separately.
