This is an industrial media converter that converts 1 10/100/1000Base-TX(RJ-45) to 1 1000Base-LX(FC) via 1310nm single-mode fiber (SMF) FC, with a maximum distance reach of 20km. This provides a cost effective conversion from 10/100/1000Base-TX(RJ-45) to 1000Base-LX fiber, while extending the network reach beyond the 100m reach limitation of copper. This industrial grade product includes a terminal block and does not come with a power plug. 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.This is an industrial media converter that converts 1 10/100/1000Base-TX(RJ-45) to 1 1000Base-LX(FC) via 1310nm single-mode fiber (SMF) FC, with a maximum distance reach of 20km.
