This Third Edition has new graphics and test results. The study considers all popular fiber optic cleaning tools. These include IBC, Sticklers, FerruleMate, CleTop, and QbE products. The work is not intended to draw a conclusion: this is up to the reader. There are "winners and losers" but it's also important to remember that this evaluation is a baseline for your decisions. You will be shown how to use any product and have it work better. There is an important section on IEC Standards and how these ten year documents are outpaced by technology. There are recommendations on how to create your own standard and why this may be important for specific installations in specific geographical locales. Finally, you are invited to submit your "tough nut" problems to be resolved.
