TYPE: The event type. See Table 11.
Notes
The OTDR Port and End events always show N/A
for loss because backscatter measurements are
not available on both sides of those events.
If an event shows “---” in the LOSS and REFLECT
columns, the tester did not find the event at the
selected wavelength. Tap an arrow button (
) to
see the measurements for the other wavelength.
Tap
to see help for this screen.
OVERALL: Tap this button to see overall measurements of
length, loss, and optical return loss for the fiber.
When more than one button shows at the bottom of the screen,
the tester highlights one in yellow to recommend which one to
tap. See “Buttons to Do Tests and Save Results” on page 53.
If the tester made measurements at two wavelengths, tap the
arrow buttons to see results for the other wavelength. Possibly,
some events show only at one wavelength.
: The measurement is within the limit.
: The measurement exceeds the limit.
: The tester does not give a pass or fail result to the event. This
occurs for OTDR Port, Hidden, and End events. This occurs for all
events if you use the Document Only test limit because
Document Only does not have values for limits.
When you use a test limit that has a reflectance limit, Hidden
events show a fail status if their reflectance exceeds the limit.
To see details for an event, such as limits for measurements and
the SEGMENT ATTENUATION coefficient, tap the event in the
table.
