10/100M Fiber Ethernet Media Converter..

10/100M single mode single fiber media converter

Model Number: TELELFY-110S-20A/B


  • In conformity to IEEE 802.3 10 Base-T standard.
  • In conformity to IEEE 802.3u 100 Base-TX/FX standard.
  • Max. 2M buffer memory built in chip.
  • Back pressure flow control for full duplex
  • IEEE802.3 X and half duplex.



    10/100/1000m fiber optical media converter can convert Optical-Electric Ethernet signals between 10/100/1000M UTP interface (TX) and 1000M optical fiber interface (FX). The traditional 10/100/1000M gigabit Ethernet can be extended to the distance of 100km through optical fiber link. The performance and quality of the products are excellent because of adopting latest Gigabit IC from USA and Taiwan. 6 Group LED indicated lights could fully monitor the working conditions of converters. It is easy for users to observe and diagnose the failure of converters. GT Series Gigabit Converters could be used alone; but Converter Card should be inserted to 16 slots RACK supplied by G.T. Crop. which is suitable for the use of Network Centre.
