Testing your fiber optic installation involves a whole separate set of issues than copper wiring. With our fiber testers, you can find the tools to help you accurately measure power loss and pinpoint problems, locate fiber breaks and bend losses, measure cable length and integrity, as well as peaks and valleys in light frequencies, and much more. Whether you're dealing with single or multimode fiber optic cables, we're sure to have the tester you need to ensure your project will have the best possible connection.
