High-definition multimedia surveillance applications, often need to be HD uncompressed digital audio and video signal source long-distance transmission. But long-distance transmission using conventional cable, there is always the output signal is poor, vulnerable to interference phenomena. Simultaneous transmission distance is short, can not meet the multimedia information requirements for long distance transmission and other occasions, the use of HDSDI-T / R Optical transmission HDSDI signal, completely solve such problems, the transmission distance of 1 m -20 km. Meanwhile, Optical transmission with low attenuation, bandwidth, interference situation, high safety performance, small size, light weight, etc., it has incomparable advantages in terms of long-distance transmission and special environment. In addition, HDSDI equipment in the multimedia system applications, which saves construction costs and the complexity of the line to go, but also to ensure high-quality target possible.



Applicable for :

  1. Long-distance transmission of military exercises HD video signal
  2. Security monitoring high-definition video signal long-distance transmission
  3. HD video signal transmission in large-scale performances
  4. A variety of high-definition video should occasion






  1. RS485, reverse direction.
