Extend Network Distance- Used In Pairs, This Media Converter Can Extend Distances Between Two Twisted Pair Switches Or A Switch And A Server upto 2 km Over Multimode Fiber, Or upto 120 km Over Single-mode Fiber, Connect Remote Devices- Using One Media Converter, A Switch With A Copper Port Can Be Connected To A Switch With An Existing Fiber Interface


  • Operates under heavy traffic loads without excess heat, so there is no need for a failure-prone internal fan
  • Round trip delay of only 40 bit times, far below the Class II rating of 92 bit times
  • Auto-negotiation (802.3u)- Allows devices to perform automatic configuration to achieve the best possible mode of operation over a link
  • AutoCross(TM)- Automatically detects and configures the twisted pair port on the converter to the correct MDI or MDI-X configuration
  • Link pass through is a troubleshooting feature that allows the media converter to monitor both the fiber and copper RX ports for loss of signal
  • Far End Fault (FEF)- A troubleshooting feature that is generally used in conjunction with link pass through to notify both end devices of a loss of link
  • Automatic link restoration- Transition Networks converters will automatically re-establish link in all network conditions
  • Pause (IEEE 802.3xy): Pause signaling is an IEEE feature that temporarily suspends data transmission between two devices in the event that one of the devices becomes overwhelmed
  • The converters will also automatically re-establish link when connected to two 10/100 auto-negotiating switches if link is lost. With other manufacturers’ converters the user must intervene to re-establish link
