20km Optical Fiber Ethernet Media Converter Modem Protocol E1 Interface

Model: LNK-EF001

Overview

This device provides one E1 interface and one optical interface to achieve interface conversion, rate conversion and timeslot extraction from E1 to Optical. When unframed mode, the data channel rate is 2.048Mbps. The device has inter-set loop test function to facilitate the project launching and daily maintenance.
