● 64 channel telephone optical transceiver can transmit 64 channel telephone through optical fiber. The special digital multiplex chip adopted by the equipment integrates almost all the digital logic functions in the equipment, which significantly improves the performance of the product and reduces the cost
Cost. The equipment has excellent performance, stable and reliable operation, low power consumption, high integration, small volume and easy installation and maintenance. Professional telephone module and PCM pulse code modulation technology are adopted, with clear voice quality,
The call is stable and reliable. Each voice signal has a three-level overcurrent and overvoltage protection unit, which is different from the equipment with unclear voice and unstable call produced by the channel of video optical transceiver.
