Principle of Bending and Twisting of Optical Cable Joint Boxes
Excessive bending causes light leakage from micro cracks in the fiber cladding, resulting in data loss and signal attenuation. Fiber optic cable bend radius is a critical mechanical parameter that determines how sharply a cable can be bent without risking microbending, macrobending, signal loss, or long-term structural fatigue. So an important question arises:. Fiber cable is designed to be pulled with much greater force than copper wire if pulled correctly, but excess stress on the cable may harm the fibers, potentially causing eventual failure. Particular care should be taken during installation to prevent kinking the cable which can harm the fibers. If you bend the cable tighter than the critical bending radius, you risk breaking the fibers inside or. The information contained in this manual should serve as a guide to proper handling, installing, testing, and for troubleshooting problems with fiber optic cables.
