description

8-32-channel telephone + 4-channel 100M network PCM telephone optical transceiver

Rackmount 8-32-channel telephone + 4-channel 100M network PCM telephone optical transceiver adopts large-scale integrated circuit with independent intellectual property rights, applies time-division multiplexing technology, and transmits Ethernet signal and telephone signal on a pair of optical fiber after mixing and coding. It realizes 10/100M Ethernet service, telephone service and mixed transmission, and the transmission channel is an optical transmission channel. The machine adopts 1U rack-mountable equipment design with high integration, small volume, low power consumption, reliable work and easy installation and use.
