Yes, fiber cables can be bent during installation, which proves particularly useful when you pull cables into position rather than using blown installation methods. Blown fiber installation uses air pressure to propel cables through conduits, minimizing bending stresses. 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. The minimum bend radius defines the smallest.
