Working in FTTx Mode

14

5 Working in FTTx Mode

You can use this mode during service activation (at ONT) or to troubleshoot passive
optical networks (at ONT, drop terminal, fiber distribution hub or CO). You can
measure two or three wavelengths simultaneously, depending on the configuration
of the unit.

Selecting a Threshold Set

You can select which threshold set will be used to determine the Pass/Warning/Fail
status. Your unit contains up to 10 threshold sets, but only one set can be selected at
a time.
Depending on the model of the unit, a threshold set comprises two or three
wavelengths (1310 and 1490 nm; 1310, 1490, and 1550 nm), each of them having
specific threshold values for pass, warning and fail.

Note:

Thresholds are used in Pass/Fail mode only.

You can view thresholds directly on your unit. To modify threshold values, you must
use the Handheld Data Transfer (refer to the Handheld Data Transfer online help).
