Note: This function is available only with the optional FTTx software package.
The application offers you a special testing feature to rapidly locate fiber
ends. It also displays the length of the fiber under test.
The unit will determine the more appropriate wavelength (singlemode or
multimode, depending on your test configuration). Duration of the
acquisition is 45 seconds.
If you intend to test at multimode wavelengths, carefully read Launch
Conditions for Multimode Measurements on page 50.
To acquire traces in Fault finder mode:
1. Clean the connectors properly (see Cleaning and Connecting Optical
2. Connect a launch fiber between the device under test and the OTDR

AUTION
Never connect a live fiber to the OTDR port without a proper setup.
Any incoming optical power ranging from –65 dBm to –40 dBm will
affect the OTDR acquisition. The way the acquisition will be
affected depends on the selected pulse width.
Any incoming signal greater than –20 dBm could damage your
OTDR permanently. For live-fiber testing, refer to the SM Live port
specifications for the characteristics of the built-in filter.
