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 DVB­ASI 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.

1 SAFETY INSTRUCTIONS

THE 3257 SYSTEM MAY CONTAIN A CLASS IIIb LASER. PLEASE OBSERVE THE
FOLLOWING SAFETY PRECAUTIONS THAT APPLY TO LASER EQUIPPED UNITS.

WARNING: Do not disconnect the fiber optic external connector with the power turned
on. Exposure to Class IIIb Laser radiation is possible when the external fiber connector
is disconnected while the unit is still powered up. Ensure the rubber boot is in place
whenever the fiber optic cable is disconnected.

CAUTION: Attempting to make adjustments or performing operations other than those
specified may result in hazardous radiation exposure. Exposure for only seconds can
cause permanent eye damage as well as other injuries.
