Item Description
OVERALL LOSS The end-to-end loss of the cabling, excluding the OTDR connection and the end event. The
loss does not include launch and receive fibers if launch and receive fiber compensation are
enabled.
Note that OVERALL LOSS does not include the losses of the first and last connectors in the
cabling if you did not use launch and receive fiber compensation.
If the test ran at two wavelengths, the highest loss of the two wavelengths is reported.
LARGEST EVENT The largest loss event on the cabling.

OTDR DETAILS screens to switch between overall results details and event
details.
