HD-AHD
Video/Audio/Data Fiber Optical Transmitter and Receiver
BRIEF
INTRODUCTION
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.
