Functional Description - Optelecom-nkf 9131DT Installation And Operation Manual

Functional Description

The Model 9131DT Multiplexer/Transmitter combines four composite video baseband signals by
implementing a 10-bit linear analog-to-digital conversion on each video signal at a 15 MHz rate, combining the
signals with three input data signals using Time Division Multiplexing (TDM) techniques and transmitting the
data via one optical fiber.
The Model 9131DR receives the optical signal from the transmitter, separates the composite data into four
digital video data streams and three data streams, does an digital-to-analog conversion of the four video data
streams yielding four composite video outputs and three data outputs.
The 9131DT and 9131DR are compatible with the 9000 series card chassis, occupy one card slot each, and
operate on 6 VDC from the appropriate chassis power supply.
