have damage. Use the VFL to make sure the fiber under
test has continuity.
If you are connected to fibers at a patch panel that are
connected together at the far end, and you are not sure
you are connected to the correct fibers, connect the
main tester’s INPUT fiber to different connections until
the test continues.
