7 Testing Fibers in Template
Mode
Template mode allows you to test fibers and compare them to a reference
trace that was previously acquired and analyzed.
Template Principle
Cables contain numerous fibers. Theoretically, on all these fibers, you will
find the same events at the same location (due to connectors, splices,
etc.). Template mode allows you to test these fibers one after the other
quickly and efficiently and ensures that no event remains undetected.
The Template mode concept is to acquire a reference trace (template),
add information and comments on the current job, then save the trace.
For a more accurate reference trace, you can update it with new events
that may occur during the first acquisitions (up to fifteen).
The test application will flag possible problems and discrepancies between
the reference trace and other traces.
Each new acquisition will be compared to the reference trace and the
software will mark and measure any missing event.
If the reference trace was created with the ToolBox software on an
FTB-500 or a computer, the event-related comments inserted in the
reference trace, as well as the reference trace report, are automatically
copied to subsequent traces.
Note: You cannot add comments to events or to a reference trace.
