DATA TX
A green LED indicator is provided to monitor the data coming in from the electrical interface,
through the RR-482D-1470/1490, and out onto the fiber. The intensity of this indicator will vary
with input data patterns, however in typical applications it will cycle on and off as data is
transmitted. Data transmitted status associated with this LED is summarized below.
