7. If your OTDR supports singlemode, singlemode live, or multimode

wavelengths, under Wavelengths, from the list, select the desired fiber

type (for live-fiber testing, select SM Live; for C fiber, select 50 μm and

for D fiber, select 62.5 μm).

8. Select the boxes corresponding to the desired test wavelengths. You

must select at least one wavelength.

9. Select the desired distance, pulse, and time values. For more

information, see Setting Distance Range, Pulse Width, and Acquisition

Time on page 45.

10. Press Start or from the keypad. If the first connector check

feature is enabled, a message will appear if there is a problem with the

injection level (see Enabling or Disabling the First Connector Check on

page 28).

You can modify the acquisition parameters as needed, while the

acquisition is in progress. The OTDR simply restarts the averaging each

time a modification is made.

11. Once the analysis is complete, save the trace by pressing Quick Save

in the button bar or from the keypad.

The application will use a file name based on the autonaming

parameters you defined (see Naming Trace Files Automatically on

page 24). This file name appears at the top of the graph and at the top

of the linear view table.
