Using the OTDR as a Light Source
188 FTB-700 Series
To use your OTDR as a source:
1. Clean the connectors properly (see Cleaning and Connecting Optical
Fibers on page 22).
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.
