Multi-channel Video/Audio/Data/ETH Optical Add/Drop

Multi-channel Video/Audio/Data/ETH Optical Add/Drop

Brand name:

Product introduction




The product is a fiber optical digital uncompressed multiplexer for transmitting 2 to 64 channels of uncompressed high quality video, bi-directional audio and data, 4 E1 and 10/100M Ethernet over two fibers.

It provides multiply optical ports to receive the video, audio and data from video transmitter and multiplex all of these video, audio and data into two fibers.

It supports daisy-chain and ring topology, with the video add/drop multiplexing technology, which makes it insert local video, audio and data into the transmission optical fibers, or drop the video, audio and data from the transmission optical fibers directly. The other video, audio and data will pass through without interference. With the technology, it provides a cost-effective solution for multiply equipments cascading and extending the transmission capacity up to 128 channels audio, video and data over a single fiber, or 256 channels over two fibers.

For the ring topology, it provides the feature of 1+1 transmission fiber protection and APS (Auto-Protection Switch). If one of the fiber is broken, the equipment will detected it and switch to another transmission path automatically without interrupt, which makes the data transmission with high stability.

At the receiving side, the de-multiplexer extracts all of video, audio and data from transmission optical fibers and output by the corresponding interfaces. The video, audio and data will be put into the cross connection device, for example, the video matrix, and then to be displayed on the screen or TV wall.

Applications for this product series include CCTV, video surveillance, ITS and etc.
