Low Consumption SX EOC Slave Serial Port Modem
Product Overview of Low Consumption SX EOC Slave Serial Port Modem
FC-FM1 use mini type structure, Each device provides E1 transmission channel in fiber, including clock extraction and transmission, can interworking with single E1 network bridge, can compose star network with centralized light cat. Can be used for LAN interconnection, video on demand, remote monitoring and other areas. E1 time slots can be settable with dip switch.
Product Features of Low Consumption SX EOC Slave Serial Port Modem
l Can detect the reason of optical signal losing is that the device power-off or transmission fiber broken
l Provide 2 impedances: 75 Ohm unbalance and 120 Ohm balance;
l After strict testing and practical verification system, completely comply with protocol ITU-T V.35, G.703, G.704
l The hardware realizes any one of 31 time slot any time slot optional (valid when framed)
l 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)
l Have pseudo random code test function, easily line opened, can be used as a 2M BER Tester
l AC 220V, DC-48V, DC+24V, DC Power and Polarity-Free
