This article exposes some of the limitations of copper testers when it comes to testing fiber-optic links and outlines the reasons why true fiberoptic test instruments should be preferred. Contrary to copper cables, characterizing and certifying the optical fiber found in premises networks is quite simple, as it rests within one main parameter: assessing the loss (or attenuation) occurred in the link, and making sure it is lower than the maximum acceptable loss level specified by the cable manufacturer, the network designer or the governing standards bodies. What’s not so simple is choosing the right test instruments, the ones that will provide the field technician with accurate, reliable results.
