PLANET MFB-TFX SFP transceiver 1310 nm

The PLANET MFB-TFX is a 100Base-FX SFP transceiver operating at 1310 nm over multi-mode fibre. It is built for network operators who need a 2 km link in industrial temperature ranges. The module fits any SFP MSA-compliant port and meets IEEE 802.3u and FDDI ISO/IEC 9314-1 standards.

Installing the transceiver and avoiding pitfalls

Installation follows the standard SFP hot-plug procedure: insert the module until it clicks, then connect LC duplex patch cords. The LC latch can snag on adjacent ports if the cage is crowded; clear neighbouring modules first. Verify the host device recognises the Serial ID data to confirm correct seating and compatibility before passing traffic.

The specification that decides fit

The 125 Mbps 100Base-FX transfer rate is the single parameter that determines whether this transceiver matches the link. It will not operate at gigabit or 10 Gbps speeds, and it requires multi-mode fibre terminated with LC connectors. Buyers needing higher bandwidth or single-mode reach beyond 2 km must select a different module.

Questions about this item

How can I verify the 1310 nm transceiver is operating correctly after installation?

Check the link LED on the host port and confirm a steady 100Base-FX connection over the LC multimode fiber up to 2 km.

What comes in the box and what must be purchased separately?

The transceiver itself is supplied; LC duplex patch cables and compatible multimode fiber are not included.

Which version should I choose for a 2 km multimode link at 125 Mbps?

The MFB-TFX model covers 2 km on multimode fiber at 1310 nm with an operating range of -40 to 75 °C.
