The importance of fiber cabling testing for high-speed optical applications

by www.fiber-mart.com Twenty years ago, when I began working on communications infrastructure projects, testing equipment was simple and had limited functionality. Screens were monochromatic, the battery did not last long, and there was no software to manage reports. Performing tests was really a challenge: not only the test itself, but [ Continue reading…]
