This is an industrial media converter that converts 2 10/100Base-TX(RJ-45) to 2 100Base-FX(SC) via 1310nm multi-mode fiber (MMF) SC, with a maximum distance reach of 2km. This provides a cost effective conversion from 10/100Base-TX(RJ-45) to 100Base-FX fiber, while extending the network reach beyond the 100m reach limitation of copper. Our media converters and network interface cards are 100% compliant for all of our networking needs. Now you have a cost effective solution to your network upgrade needs.
