Overview
The S751DA and S7751DA fiber links provide two-way
transmission of audio, multiprotocol data, and contact
closure over one or two single mode or multimode fibers.
Digital Processing
Digital processing of the audio signal along with an audio signalto-noise ratio >90dB allows the audio output to drive balanced
or unbalanced loads and maintain constant audio levels.
Data Translation
The data functions include the unique data translation feature,
which allows one data format to be input and a different data
format to be output. Data formats are selected during installation
and can be easily changed in the field via rotary switch.
Superior Diagnostics
The SMARTS™ diagnostic technology provides an extensive
set of diagnostic tools including an audio test generator
to verify audio channel operation. LEDs provide a visual
indication of the operating status of the audio, data, and
contact channels as well as the optical signal strength.
