Description
The rack-mountable MX3257HD fiber optic video
multiplexer is ideal for transmitting 1 channel of video, 2
channels of audio and 1 high speed serial data channel
on one fiber optic cable.
The high speed serial data channel may be either DVB-
ASI or SMPTE-310M. The MX3257HD's High Speed
Serial data channel employs automatic cable
equalization for error free operation over long coaxial
cable runs.
The MX3257HD operates by digitizing and multiplexing
video, audio and high speed data onto a high-speed
serial data stream, which is then transmitted via fiber
optics.

Because the system employs digital transmission
techniques, performance characteristics are consistent
and maintained over the specified distance with no
degradation of signal.
The MX3257HD is designed to work with standard
singlemode or multimode fiber optic cable and can be
wall mounted or rack mounted. Both transmitter and
receiver come equipped with internal power supplies.
Optical Link LEDs facilitate the continuous monitoring of
the fiber optic system.
