The OFL250 OTDR offers five modes of operation: Full Auto, End Locate, Live, Expert, and Light
Source & Power Meter mode. The Mode setting determines which other settings may be changed
by the user and which are set by the OFL250 automatically. Each OFL250 mode is described
below:
Mode Description
Full Auto This is the recommended mode for users who are not familiar with OTDR
operation. In the Full Auto mode, OTDR parameters such as Range, Filter,
Pulse Width, and Averaging Time are set automatically. Full Auto tests include
an Event Table and Information Page.
End Locate As in the Full Auto mode, End Locate mode offers automatic OTDR setup but
replaces the Event Table view with the End Locate view to indicate the fiber
end location in user selected units of measure.
Live This is the best mode for real-time troubleshooting. In the Live mode,
Wavelength can only be set to individual wavelengths.
Expert This mode is available for experienced users. It provides the most set
up flexibility. You can set Range, Filter, Pulse Width, and Averaging Time
manually (Auto Setup = Off) or automatically (Setup = By Range).
Light Source and
Power Meter
This mode allows you to perform Light Source and Power Meter
measurements.
