DLX-HDVOP-A series of products adopts ASIC and advanced digital video, high-speed TDM and Gigabit CWDM technology to provide uncompressed high quality transmission systems for 1-16channels 1280H/25f,1280H/30f,1280H/50f,1280H/60f,1920H/25f,1920H/30f etc format HD-AHD video and up to 32 channels of bi-directional data and audio signals over one single mode or multimode optic fiber. Support transmission of broadcast grade 24bit CD HI-FI audio and high-speed data. Support auto-adapt to 1280×720 and 1920×1080 resolution(only 1920H type). Compared with the same kind of analog transmission systems that employ accidental amplitude or frequency modulation, DLX-HDVOP-A products provide better transmission in quality. Support network of tree structure, star structure, ring structure and topology etc. DLX-HDVOP-A adopts Modularized design, support function expanded.In the HD video application system, if use common copper cable for long distance transmission, it will always show the poor output signal, be liable for the interference, the image displayed appears the phenomenon of the vague, the tailing and color separation etc. At the same time, the distance of transmission is short, it can not meet the requirement of long distance transmission for the multimedia information issuing etc. using the DLX-HDVOP-A optical transmitter and receiver for transmitting HD-AHD signals, this kind of problem has been completely solved, the distance of transmission is from 1km to 80km. In the mean while, the optical transmitter and receiver has the outstanding points with a little attenuation, frequency bandwidth, strong anti-interference, high safety performance, small volume and light in weight etc., therefore, it has incomparable advantages in the respect of the special environment and the long distance transmission.
