The rackmountable MAX3257HD fiber-optic baseband video multiplexer from Maxcom is ideal for transmitting a single channel of baseband video, two channels of audio, and one high-speed serial data channel on one strand of fiber-optic cable. The high speed serial data channel employs automatic cable equalization for error-free operation over long coaxial cable runs, and it may be either DVB-ASI or SMPTE 310M.

The multiplexer operates by digitizing and multiplexing video, audio, and high-speed data onto a high-speed serial datastream, which is then transmitted via fiber-optic cable. Because the system employs digital transmission techniques, performance characteristics are consistent and maintained over the specified distance with no degradation of signal.

The MAX3257HD is designed to work with standard single-mode or multimode fiber-optic cable, and the unit can be wall-mounted or rackmounted. Both transmitter and receiver come equipped with internal power supplies. Optical-link LEDs facilitate the continuous monitoring of the fiber-optic system.

Other features include high-quality 10-bit digital sampling of video input, digital transmission of stereo audio, baseband video or composite video/audio transmission over video channel, external audio compatible with balanced or unbalanced audio formats, high-quality uncompressed digital transmission, and an SNR of 67dB. Bidirectional transmission is also available.
