General information
The Loss test operation is used to measure loss of a fiber loop or
any optical component connected to the loop. When running a
loss test, the internal laser source and powermeter are locked.
Compared to the Loss/Length test operation the Loss mode
allows real time measurement (values and changes are displayed
while measuring) and can be run easily by setting up just a view
parameters. On the other hand, limits must entered manually
(there are not calculates as for Loss/Length) and only loopback
measurement is possible.

Following table may help you to choose the right operation
mode for your measurement task.
You want to ...
... measure loss and length
... measure just loss with editing reference
and limit
... measure margin
... specify cable parameters and calculate
limits
... measure loopback (e.g. Component
Test)
... measure remote
