the wavelength and display [Length], [Loss]
and [ORL] test results for that wavelength.

ICON EVENT TYPE DESCRIPTION
Macrobend A non-reective loss event with signicantly higher loss at longer wavelengths (1550,
1625, 1650 nm) than seen at shorter wavelengths (1310, 1490 nm). Typically caused
by a sharp bend in the ber.
Splitter PON splitters are detected only when Event thresholds are set to PON Default or PON
User and a high loss event (> 6 dB) is detected which is determined not to be the end
of the ber.
Group Start
Event
First event in multiple event group. Reports loss of entire group. Reports
reectance of rst event in group if reectance of next event can be independently
measured. Reports max reectance of grouped events if next reectance cannot be
independently measured.
Group
Middle Event
Grouped events may contain zero, one, or more middle events. Loss of middle events
is included in group loss reported in the group start event. Reports reectance if it
can be independently measured.
Group End
Event
Last event in a multiple event group. Loss of last event is included in group loss
reported in group start event. Reports reectance if it can be independently
measured.
