The 4-way telephone optical transceiver can transmit 4-way telephones through fiber optics. The equipment uses a dedicated digital multiplexer chip, which integrates almost all digital logic functions in the equipment, significantly improving product performance and reducing costs
Ben. The device has excellent overall performance, stable and reliable operation, low power consumption, high integration, small size, and is easy to install and maintain. Using professional telephone modules and PCM pulse coding modulation technology, the voice quality is clear,
The communication is stable and reliable, and each voice signal has a three-level overvoltage protection unit, which is different from devices that produce unclear voice and unstable communication through the channel of video optical terminals.
No compression, good voice quality.
