Testing in Auto Mode

The application will automatically evaluate the best settings according to 
the fiber link currently connected to the unit (in less than 5 seconds).

By default, fiber characteristics are evaluated each time you start a test. 
This is particularly useful if you often have to test fiber links of different 
lengths. 
If you prefer, you can set your unit to keep the same settings (range and 
pulse) for all acquisitions. This could be useful if you need to test several 
similar fibers (same length) within the same cable. It is always possible to 
reset the fiber settings later.

If you intend to test at multimode wavelengths, carefully read Launch 
Conditions for Multimode Measurements on page 49.

To acquire traces in Auto mode:
1. Clean the connectors properly (see Cleaning and Connecting Optical 

2. Connect a launch fiber between the device under test and the OTDR 

port. If necessary, set the 

 (see Setting Analysis 

If your unit is equipped with two OTDR ports, ensure that you connect 
the fiber to the appropriate port (OTDR SM, OTDR MM, or 
OTDR SM Live for filtered wavelength).
