Setting Pass/Fail Thresholds

You can define five groups of thresholds to specify acceptable loss (in dB

and dB per distance unit) and ORL values (in dB) for each wavelength, for

both singlemode and multimode fibers.

Thresholds are supplied by system manufacturers and depend on the

system deployed.

Each time a measurement exceeds a threshold, the result is shown with a

red background and an exclamation mark in the table.

Note: When transferring results from handheld unit to computer, thresholds are

not transferred along with results. However, you can define thresholds in

the Optical Report Viewer application.

IMPORTANT

Thresholds are not saved with measurements. Results are compared

to the threshold group currently active on the unit where results

are viewed (for F

ASTEST results, not necessarily the master unit).
