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 100m 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.
