Manufacturer Contact Info

The PLANET MFB-TFX is a 1310 nm, LC-port SFP transceiver for 100Base-FX links up to 2 km over multimode fiber, suited to network operators adding or replacing compatible fiber links in equipment that supports this SFP.

Recommended For

Network technicians replacing an existing 100BASE-FX multimode link who need a 1310 nm SFP for a compatible host and a link distance of up to 2 km.
Industrial network installers working in locations with wide temperature swings who need a 100BASE-FX SFP rated for extended-temperature operation.
Facilities teams maintaining older switches, controllers, or other equipment with native 100BASE-FX SFP ports that need a like-for-like multimode fiber replacement.
IT teams linking compatible 100BASE-FX equipment over multimode fiber when a 100 Mbps fiber connection meets the network’s throughput needs.

Real-World Use Scenarios

A maintenance team is replacing a failed optic in a compatible 100BASE-FX industrial switch. Installing the MFB-TFX can restore the existing multimode fiber link without changing the network to a different Ethernet speed.
A facility needs to connect industrial switches across an existing multimode fiber run. When the run and both devices support 100BASE-FX and are within the transceiver’s reach, the MFB-TFX provides a fiber link without replacing the installed cable.
A plant operator is linking network equipment in separate areas, such as a control room and a production floor. The fiber connection can carry the existing 100 Mbps Ethernet link between compatible 100BASE-FX ports, subject to the installed fiber path and its condition.
A switch or media converter is installed in a location with large temperature swings. In equipment that supports the MFB-TFX, its extended-temperature design can suit harsher operating environments than a standard-temperature optic; the actual device and enclosure limits still need to be checked.
A technician needs to add or replace the optic while network equipment remains powered. PLANET describes the MFB family as hot-pluggable, allowing installation or removal from a supported SFP port without powering down the switch or media converter.
