Framed E1 to Fiber Converter
Framed E1 to Fiber Converter Advantage
· Based on self -copyright IC
· Can detect the reason of optical signal losing is that the device power-off or transmission fiber broken
· Provide 2 impedances: 75 Ohm unbalance and 120 Ohm balance;
· After strict testing and practical verification system, completely comply with protocol ITU-T V.35, G.703, G.704
· The hardware realizes any one of 31 time slot any time slot optional (valid when framed), 1-32 can choose any open slots
· Have three Loop Back Mode: E1 interface Loop Back (ANA),V.35 interface Loop Back(DIG),Command the remote V.35 interface Loop Back(REM)
· Have pseudo random code test function, easily line opened, can be used as a 2M BER Tester
· AC 220V, DC-48V, DC+24V, DC Power and Polarity-Free
· FE1 fiber modem can use with V.35 fiber modem, that can save a G.703/V.35 converter
Framed E1 to Fiber Converter Overview
This device provides one Framed 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.
