MFB-Series Transceiver 100BASE-FX SFP Transceiver

The MFB family consists of SFP (Small Form Factor Pluggable) transceiver modules that are specifically designed for high-performance integrated duplex data links over single-mode optical fiber. These transceiver modules comply with the SFP Multisource Agreement (MSA) and are hot-pluggable. These modules offer an easy way to be installed into SFP MSA compliant ports at any time without interrupting the operation of the host equipment.

MFB SFP transceivers using a long wavelength (1310nm) FP LD allow data transmission up to 2km over multimode optical fiber and up to 60km over single-mode optical fiber.

To meet the growing demand for industrial Ethernet fiber solutions, Planet has released the MFB-T 100Base-FX transceiver series which can operate reliably in electrically harsh, climatically challenging environments and with a wide temperature range (-40℃ to 75℃). The MFB-T 100Base-FX transceiver series provides an easy and fast 100Base-FX link for Planet's wide-temperature industrial equipment.
