Performance Monitoring
When a new line is installed you may want to monitor performance
for a day or so to be sure it is operating correctly. Or, if problems are
suspected on a line, you may want to run a long test to determine the
cause of the problem. In either case, the CTS850 makes it easy to
monitor an electrical or optical line without the need for splitters.
During a test, the CTS850 simultaneously takes all performance
measurements, analyzes the results according to the G.821 standard,
and displays the measurements and analysis in your choice of three
formats:
H
In a brief summary
H
In detail by type (defect, anomaly, alarm, failure)
H
In detail by layer (regenerator section, multiplexer section, path)
In this example, the CTS850 is placed directly in line with a live
optical signal to monitor performance in an unintrusive mode
(Through Mode).
1. Connect the CTS850 in line with an optical signal as shown in
Figure 3–7.
