Product Details
E1 to Optic Fiber Converter
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.
Features
- Based on self -copyright IC
- Can detect the reason of optical signal losing is that the device power-off or transmission fiber broken, and indicate on LED
- 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
- 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
