10/100M Singlemode Single Fiber Media Converter can convert Optical－Electric Ethernet signals between 10/100M UTP interface (TX) and 100M optical fiber interface (FX). It could extend traditional 10/100M Fast Ethernet to the distance of 120km through single optical fiber link. It possesses stable performance and good quality by adopting latest IC from USA and Taiwan. It must be used in couples，because the transmitted optical differs from the receive optical in wavelength. 3 Group LED indicated lights could fully monitor the working conditions of Converters. It is easy for users to observe network operation.

Main features
◆The transmission of a channel optical signals can be completed by single fiber. It has doubled in quantity of fiber data transmission compared with twin fiber type.
◆Auto negotiation function allows UTP port to auto select 10M or 100M and Full Duplex or Half Duplex
◆The UTP port supports MDI/MDI-X auto crossover.
◆Supporting 1600 bytes packet for management.
◆Internal circuit of prevented thunder could greatly reduce damage of converters caused by thunderbolt induction.
