1Ch Unframed E1 to Fiber Converter

型号:LNK-EF001 Series

Based on self -copyright  IC 
Provide 2 impedances: 75 Ohm unbalance and 120 Ohm balance;
►Completely comply with protocol ITU-T V.35, G.703, G.704
Have pseudo random code test function, easily line opened, can be used as a 2M BER Tester

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.

Features

Based on self -copyright  IC
