Ho-Link this device uses a special digital multiplexing chip, which integrates almost all digital logic functions in the device, thus significantly improving the performance of the product and reducing the cost. The equipment has excellent performance, stable and reliable operation, low power consumption, high integration, small size and easy installation and maintenance. A single optical fiber can transmit 2 channels of telephone signals. Our company has the core technology, the use of PCM pulse coding modulation ......
Features
1. Provide 2 channels telephone interface
2. Use of audio frequency transformer and photoelectric coupler to completely separate the telephone interface and other circuits
3. Voice interface support caller ID and provide polarity reversal signal
4. Each voice signal has three levels of over-current voltage protection
5. Conventional standard single mode transmission 20KM, multi-mode 1KM, the farthest single mode can be customized up to 100KM
6. Single fiber / dual fiber transmission (optional)
7. No compression, no delay, high fidelity speech
8. Plug and play, no debugging
9. Perfect LED status display function, easy to maintain and manage
10. The device distinguishes between transmitter and receiver, and the label distinguishes the relay switch and the telephone
