OSA 271
Managing WDM Test Results
WDM Investigator Tab
The WDM Investigator tab presents information allowing you to do massive
network prevention and maintenance. With the WDM Investigator
dashboard, an OSA can identify several types of impairments on a
per-channel basis, which gives visibility into a WDM network. In addition,
the WDM Investigator dashboard provides useful information on the
channel characteristics.
Note: If your measurement file contains diagnostic information, the latter will be
stored in the file when you save it. It will be possible to view the diagnostic
information later with the OSA application (the WDM Investigator (Inv)
option is not required to view the stored file). You can also view the same
information with the offline application.
Channel diagnostics and the WDM Investigator tab are only available for
the active trace, if the two conditions below are met:
The measurement under analysis was performed on an OSA module
onto which the WDM Investigator (Inv) software option is activated.
Diagnostics are computed only for channels analyzed with the i-InBand
noise for OSNR.
