EXFO MAX-700 - Manual (Page 206)

Using the OTDR as a Light Source
194 MAX-700
To use your MAX-700 as a source:
1. Clean the connectors properly (see Cleaning and Connecting Optical
Fibers on page 42).
2. Connect one end of the fiber under test 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.
3. From the main window, press the button.
4. Select the wavelength you want to use.
Note: If only one wavelength is available, it is selected by default.
