Setting up and Operating your Distributed PMD Analyzer

34 FTB-5600

Performing an Acquisition

The FTB-5600 does a series of actions in taking a measurement.

³ The instrument takes an OTDR trace and displays it. This step only

takes a few seconds. At this point, you should inspect the trace to see if

there are any problems.

³ Then, the instrument measures the SOPs. This will take more or less

time depending on the accuracy and sensitivity requested. The

remaining time and SOPs to measure are indicated in the status bar of

the application. After measuring about 10 SOPs, you will see a

temporary cumulative PMD curve.

³ At this point, considering that the overall measurement process is quite

long, EXFO strongly recommends that you make a general inspection

of the OTDR trace to verify that the instrument is properly connected

and that the FUT is OK.

³ Once all of the SOPs are acquired, the instrument computes the actual

PMD curve.
