You can save the trace after analysis. If former results have not been saved
yet, the application prompts you to save them before starting a new
acquisition.
To acquire traces:
1. Clean the connectors properly (see Cleaning and Connecting Optical
2. Connect a fiber to the OTDR port.
If your unit is equipped with two OTDR ports, ensure that you connect
the fiber to the appropriate port (singlemode, singlemode live, or
multimode), depending on the wavelength you intend to use.

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.
