    2.048M V.35 Fiber Modem

    Type:FCP-V Message

    Description:2.048M V.35 Fiber Modem ,Equipment built-loop test function

    Product Description
                   This device provides one fiber interface and one V.35 interface to achieve interface conversion, rate conversion and timeslot extraction from fiber to V.35 interface. 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.

    Functional Properties
    Ø Based on self -copyright  IC 
    Ø Can detect the reason of optical signal losing is that the device power-off or transmission fiber broken 
    Ø The local device can forced the remote device rate follow it(valid when framed ) 
    Ø Provide 2 impedances: 75 Ohm unbalance and 120 Ohm balance;
    Ø After strict testing and practical verification system, completely comply with protocol ITU-T V.35, G.703, G.704

    Ø 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)

    Ø Have pseudo random code test function, easily line opened, can be used as a 2M BER Tester
    Ø V.35 interface supports hot-plug, supports DTE or DCE device interconnection 
    Ø Provide 3 clock types: Internal clock, External clock,E1 line clock;
    Ø AC 220V, DC-48V, DC+24V, DC Power and Polarity-Free
