Overview Telephone Media Converter :
The 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 simultaneously transmit 1~128 channels of telephone signals and 1~16 channels of 100 ethernet signals. Our company, eman Communications, has the core technology: the use of PCM pulse coding modulation technology, Voice quality is clear, stable and reliable, Each voice signal has a three-level over current voltage protection unit, widely used in government units, electric power, public security, military, civil aviation, maritime, mining, highway and other college networks or public networks.
Features of Telephone Media Converter :
- Provide a 1–128-channel telephone interface
- Support 1–16 channels 100m ethernet
- use of an audio-frequency transformer and photoelectric coupler to completely separate the telephone interface from other circuits
- Voice interfaces support caller ID and provide polarity reversal signal
- Eachvoice signal has three levels of over-current voltage protection
- Conventional standard single-mode transmission (20 KM), multi-mode (1 KM), and the farthest single mode can be customized to 100KM
- Single-fiber / dual-fiber transmission (optional)
- Nocompression, no delay, high-fidelity speech
- Plugand play, no debugging
- Perfect LED status display function, easy to maintain and manage
- The device distinguishes between transmitter and receiver, and the label distinguishes the relay switch and the telephone
