LOCATION

N/A
Item
The distance to the event, measured from the OTDR port.
The loss of each event at a wavelength. Negative dB values indicate a gain.
To measure loss, the tester determines the best-fit line between two points, using the “least
squares” method to reduce the effects of noise.
N/A is shown if the tester did not test at the wavelength. N/A is also shown if the tester could not
determine the event’s loss. This occurs for hidden events because the event's details are obscured
by the previous event's reflection. This occurs for end events because no backscatter is available
after the fiber end to compare to the backscatter detected before the fiber end.
Tip: The tester can measure the loss of the last connector on the fiber if you use a receive fiber
during OTDR tests.
