Description
Description
The analog audio fiber optic extender is to transmit 2-ch bidirectional balance audio over single core optical fiber caber to a long distance. This extender contains an electrical to optical converter and an optical to electrical converter. It takes most advantage of fiber cable anti-interference and reliability to make sure the original source audio could be transmitted to a remote place. We could supply analog audio or digital AES/EBU audio fiber box with different configurations according to your actual project request.
Features
1. 2-ch bidirectional audio over single core fiber
2. Balanced analog audio with XLR connector
3. Broadcast quality level with high integration and stability
4. FPGA solution, digital coding/decoding and clock recovery technology
5. Automatic high-pass filtering, isolation of DC offset
6. Intelligent noise control system for soft rising or falling slant waves and analog noise with 100dB SNR in blast-free operation
7. Single fiber, ST/SC/FC/LC fiber port optional
8. Single mode for 20KM standard, optional 100KM max
9. LED status indicators monitor the critical parameters
10. could be 64 channels of audio over single core fiber
11. We could make it as your requested specifications like mixing with other SDI/DVI/HDMI/DP/VGA video signal
