The MFB family consists of Small Form Factor Pluggable (SFP) transceiver modules that are specifically designed for high performance integrated duplex data link over single mode optical fiber. These transceiver modules are compliant with the SFP Multisource Agreement (MSA) and hot pluggable. These modules offer an easy way to be installed in SFP MSA compliant ports at any time without the interruption of the host equipments operation. The MFB SFP transceivers using a long wavelength (1310nm) FP LD enabling data transmission up to 2km on a multimode optical fiber and up to 60km on a single mode optical fiber. To fill the increase demand of Industrial Ethernet fiber solution. Planet releases the MFB-T series 100Base-FX transceivers that can operate reliably in electrically harsh. climatically demanding. and wide temperature range (-40℃ to 75℃) environment. The MFB-T series 100Base-FX transceivers provide easy and fast 100Base-FX connection for Planet wide temperature Industrial equipments.
