2-port Fiber Media Converter, with 1 1000Base-X SFP Slot and 1 10/100/1000Base-T(X) Ethernet Port JHA-GS11M is a Gigabit Fiber Media Converter can convert Optical－Electric Ethernet signals between 10/100/1000M UTP interface (TX) and 100/1000M 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. 2 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. Gigabit Converters could be used alone; Converter Standalone should be inserted to 14 slots RACK supplied。which is suitable for the use of Network Centre.
