| | DLX- DVOP02 series of products provide uncompressed high quality transmission systems for 2 channels of digitalized analog video, up to 32 channels of bi-directional data and audio signals, 4 channels E1/ T1 and 10/ 100M self-adaptive Ethernet data over one single mode or multimode optic fiber, DVOP is a multi-function product which based on highly reliable large-scale specialized ICs designed by ourselves. It' s extremely flexible with the ability to add/ drop video, audio, RS232/ RS422/ RS485, E1, 100M Ethernet ports via plugging in/ out our field-proven service cards. Compared with the same kind of analog transmission systems that employ accidental amplitude or frequency modulation, DVOP products provide better transmission in quality.
The numerous types of DVOP02 products can meet different user demands. Adopting advanced digital fiber optic transmission technologies, DVOP devices can be installed rapidly without customer adjusting, and they are easy to operate and maintain. On the front panel of the products are set video connector ( BNC) , audio and data connector ( RJ45) , and fiber optic connector ( FC-single mode or ST-multimode) . Users can easily monitor the status of power supply, connection and channels through the indicator lights. There are two types of DVOP02 available: standalone and card-cage packaging.
