Fiber optic cables are designed to withstand some bending, but excessive bends can physically damage the glass fiber or cause significant signal loss. That's why every fiber cable has a minimum bend radius specification provided by the manufacturer. Installers must understand these specifications and know how to install cables without. While fiber optics deliver high bandwidth and long transmission distances, their performance is highly dependent on proper physical installation. One of the most critical — and often underestimated — parameters is the fiber optic bend radius.
