OTDR Mode: Summary Page Features

Summary page displays:

trace graph, fiber under test [Length] in user

selected units, [Loss] and [ORL] in (dB).

For multiple-wavelength tests, press to toggle

the wavelength and display [Length], [Loss]

and [ORL] test results for that wavelength.

A non-reflective loss event with significantly 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 fiber.

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 fiber.

First event in multiple event group. Reports loss of entire group. Reports

reflectance of first event in group if reflectance of next event can be independently

measured. Reports max reflectance of grouped events if next reflectance cannot be

independently measured.

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 reflectance if it

can be independently measured.

Last event in a multiple event group. Loss of last event is included in group loss

reported in group start event. Reports reflectance if it can be independently

measured.
