Testing Fiber Polarity with the FiberLert™ Live Fiber Detector by Fluke Networks

Funny that I'm watching this video now and have to go to a customers site in the morning to solve the very problem illustrated in this video.

Wouldn't it be quicker just to try it and then reverse it if there's no link?

But if it doesn't come up...what do you do then? Do you switch it back the way you found it? If you don't and you replace the Module, then it won't come up...Will you remember you swapped it?
