Product Description
The DAV series digital A/V optical equipment is made up of optical transmitter DAVT and optical receiver DAVR. The input to the optical transmitter DAVT can be 1 video with 2 audios, or 2 videos with 4 audios, or 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 DAVR receiver, which outputs the high quality analog video and audio.
Features:
10bit video conversion and 20bit audio conversion
Wide dynamic video AGC supports 0.6V~1.6V video input level
Audio output can be balanced/unbalanced auto switching with ESD protection
Maximum fiber distance up to 120Km
System topology can be point to point or point to multi-point
