The GAV series digital video/audio optical equipment is made up of Greatway GAVT optical transmitter and GAVR optical receiver. The input to the GAVT optical transmitter can be 1 video with 2 audios, 2 videos with 4 audios, 4 videos with 8 audios. The analog video is converted into data in 10bit A/D and the audio is converted into data in 20bit A/D. The uncompressed muxed video/audio data is transmitted to the GAVR receiver, which outputs the high quality analog video and audio.
1) 10bit video conversion and 20bit audio conversion
2) Wide dynamic video AGC supports 0.6V~1.6V video input level
3) Audio output can be balanced/unbalanced auto switching with ESD protection
4) Maximum fiber distance up to 120Km
5) System topology can be point to point or point to multi-point
