Mini Fast Ethernet Media Converter
100Base-TX to 100Base-FX

M/E-TX Series



The M/E-TX Series is a Fast Ethernet stand-alone Mini media converter that provides cost effective media conversion between 100Base-TX ports and 100Base-FX ports. With its fixed configuration, deployments are just plug-and-play, and its small size makes it ideal for locations where space is limited. Operating at Layer 1, the physical layer, data is passed through the converter at line speed, making it ideal for applications where low latency is essential.


  • Fiber integration used in pairs or as a single unit, this mini media converter will ease the integration of fiber optic cabling into copper-rich fast Ethernet environments
  • Extend Network Distance as fiber supports the transmission of Fast Ethernet data over much longer distances than possible twisted pair
  • Low-Latency Layer 1 Design, this mini converter will retransmit Fast Ethernet signals without any store-and–forward packet inspection delays found in other Layer 2 devices
  • Small Size is ideal for conversion locations where available space is limited – 65% smaller than standard media converter
  • Unit and port LEDs allow for quick status information
  • Auto-Negotiation
  • Auto-MDI/MDIX
