FIBER INDEX
This is the index of refraction value for the fiber under test. This value
determines the speed of light in the fiber and is used to calculate distances
on the OTDR trace.
EOF EVENT THRESHOLD

F
iber backscatter threshold is the required backscatter level prior to
an event for that event to be considered as part of the fiber and not an echo
The last event with the required backscatter level is considered to be the
end of the fiber.
EVENT PASS/FAIL
If turned on, events in the OTDR event table will be highlighted in RED if they exceed the values set in the
EVENT CONFIGURATION menu.
OTDR AUTO DEAD ZONE
If turned on, the OTDR will use the first reflective event as the end of the launch cable (dead zone) and will not
include the launch cable in the fiber’s length.
TAIL REMOVAL
If turned on, the OTDR will attempt to remove any trace saturation tails caused by large reflections. This
process will take longer and slightly lower the trace backscatter level.
