BRIEF INTRODUCTION
DLX-HDVOP-S series of products adopts ASIC and advanced digital video, high-speed TDM and Gigabit CWDM technology to provide uncompressed high quality transmission systems for 1-4channels1920×1080@60Hz HD-SDI video, up to 4channels USB2.0, 1channel bi-directional RS232/RS485 and 1channel audio signals over single fiber. Each channel of SDI support 2channels SDI output, no need extra SDI distributor. RS232 can support SONY standard(optional),Support transmission of broadcast grade 1080p Full-HD video, 24bit CD HI-FI audio and high-speed data. Support active regeneration and extraction of SDI clock/data. Auto-adapt to 143Mbps,270Mbps,1.483Gbps,1.485Gbps rate and various HD or standard video. Compatible with SMPTE,SMPTE,SMPTE,SMPTE,SMPTE 295,DVB-ASI standards. Compared with the same kind of analog transmission systems that employ accidental amplitude or frequency modulation, DLX-HDVOP-S products provide better transmission in quality. Support network of tree structure, star structure, ring structure and topology etc. DLX-HDVOP-S 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-S optical transmitter and receiver for transmitting HD-SDI signals, this kind of problem has been completely solved, the distance of transmission is fromto. 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.
