HD series video Digital Optical Converter adopt the advanced international digital video and optical fiber transmission technology, and implement the transmission of real-time & synchronization, no-distortion and high quality video effect, which can meet the user’s requirement; the play-and-plug design makes the installation more convenient and easier, and it is unnecessary to implement the spot adjustment.
l module and core circuit adopt the imported components that have high stability, and all optical & electrical interfaces conform to the international standards, which is applied to the different working environment. This optical transceiver with video status indication can monitor the normal operation of system.
