What negative loss value in test result means that when I am using the fiber tester FLUKE in SM and MM fiber optics?
Some Sometimes I'm using the Fluke tester fiber optic multimode and singlemode fiber optic cables sometimes pass very well, but sometimes the "loss of negative value in the test results "appear and still seems to happen, but I do not understand why if you spend it that this" negative ", as shown in my test results and still do not know how to avoid it. I would appreciate any help. Thanks Philippe
If this is anything like the results I've seen before, this means that the filtering of light in the fiber path. It can be caused by isolation breached.
