Product Features

  • Use the built-in uplink switch to configure the UTP port: straight through or crossover!
  • Supports Link Pass-Through. A failure on either end of the link disables the link indicator on both ends.


  • Compact size enables you to tuck it into small spaces.
  • Mount multiple units in the optional Rackmount Tray.

    This Crossover Media Converter enables you to translate between twisted-pair and ThinNet or twisted pair and fiber.

    Just flip a switch to convert cable. The crossover feature is built-in, so the conversion takes place automatically—and you don't need to worry about the expense or hassle of using external crossover cables.

    The converter is small enough to fit in the palm of your hand, so it takes up very little space. For rackmounting, order the Rackmount Tray (LE1505-RACK) or the Powered Rackmount Tray (LH1505P-RACK). Each Rackmount Tray holds up to 16 media converters, and the powered model supplies power for up to 8 media converters.

    Or you can VELCRO® mount it or use metal brackets to wallmount it wherever you want—we include both of these items with the Crossover Media Converter.

  • Rackmount Tray (LE1505-RACK)
  • Powered Rackmount Tray (LH1505P-RACK)
