The optical transmitter module takes in reverse band RF signals and puts out optical 
signals. The GS7000 Node is designed to work specifically with the existing mid gain, 
temperature compensated DFB optical transmitters. Other mid and high gain optical 
transmitters may be installed in the GS7000 Node with varying effects on the overall 
node specifications. The new module cover fits on all existing optical transmitters. 
This module cover has a sliding tray incorporated into it allowing the transmitters 
fiber pigtail to be spooled up and contained within the transmitter module. This 
greatly improves fiber management within the node. 
The optical transmitter modules plug directly into the optical interface board via a 
connector header and are secured in place with two screws. Output attenuator pads 
are provided on the optical interface board for each transmitter mounted in the 
housing lid. 
RF test points are accessible through holes in the module housing. The optical power 
test point for the optical transmitter module has a scaling ratio of 1 V = 1 mW. A -20 
dB RF power test point is accessible through the module top cover. 
The top cover contains a status monitor LED. Each optical transmitter module laser 
power indicator turns off when the laser power output falls outside the alarm 
threshold. It is on (green) when within the alarm threshold.
