Optický transceiver modul PLANET MFB-FX

The PLANET MFB-FX is a Small Form Factor Pluggable (SFP) fiber optic transceiver module designed for 100 Mbit/s Ethernet links. Operating at a wavelength of 1310 nm, the module supports transmission over multimode and single mode fibers and is compliant with the SFP Multisource Agreement (MSA). It is hot-pluggable and intended for use in SFP MSA–compatible ports without interrupting host equipment operation.

Advantages

The MFB-FX provides a compact, standards-compliant SFP solution for 100Base-FX connections, offering long-wavelength (1310 nm) FP laser transmission and compatibility with both multimode and single mode fiber links. It supports hot-plug installation and is available in an industrial temperature version that operates reliably across a wide temperature range (-40℃ to 75℃), making it suitable for electrically and climatically demanding environments.

Suitable for

• 100 Mbit/s Ethernet links using SFP ports
• Short- and long-distance fiber connections (multimode and single mode)
• Industrial networking equipment requiring wide temperature operation
• SFP MSA–compliant switches, routers and media converters

Key specifications

• Interface type: SFP
• Maximum data transfer rate: 100 Mbit/s
• Wavelength: 1310 nm (FP LD)
• Reach: up to 2 km on multimode fiber, up to 60 km on single mode fiber
• Compliance: SFP MSA, hot-pluggable
• Operating temperature (industrial version): -40℃ to 75℃

How to use

Insert the MFB-FX transceiver into a compatible SFP slot on your switch, router, or media converter while the host device is powered on. Connect the appropriate fiber optic cable (multimode or single mode) to the transceiver's optical port, ensuring correct connector type and polarity. Configure the network device for 100Base-FX operation as needed; the module functions as a standard SFP optical interface.

Recommendations

Use the MFB-FX with SFP MSA–compliant ports and matching fiber type (multimode or single mode) to achieve the specified reach. For installations in harsh or wide-temperature environments, select the industrial temperature version and verify cable connectors and distance to ensure reliable 100 Mbit/s transmission.
