Maybe they checked the connector by replacing the whole fiber optic cable with a new one, and while doing that had the "oh sh.." moment of realizing the length of the old one was 20 meters different than it was supposed to be. I think this sort of thing has happened to all of us with significant experience. Or maybe the cable was marked with an incorrect length (not due to error by the experimenters) and they forgot "trust but verify". We've probably all gotten bit by that one as well.
