1GE Multi to Singlemode Converter


  • Simple stand alone converter for Gigabit multi to singlemode conversions
  • Convert 1000BaseSX to 1000BaseLX
  • Operates both with Gigabit Ethernet and 1Gbps Fibre Channel
  • Can be used alone - to converter a 1000BaseSX port on a switch to 1000BaseLX
  • Can be used in pairs - to connect 1000BaseSX interfaces on 2 switches over a span of singlemode fibre


The SFMFF1314-220 stand-alone, when used individually or in pairs, functions as a mode converter that extends Gigabit Ethernet or
Fibre Channel signals over single mode fibre up to 125 kilometers. The SFMFF1314-220 also converts 1000Base-SX ports on a Gigabit
Ethernet switch to 1000Base-LX on a port-by-port basis.
