Micro-bends can occur due to compression or pinching from which components?

• A. Panel doors
• B. Latches
• C. Other hardware
• D. Panel doors, latches, or other hardware

Answer: (D)

Micro-bends are tiny bends caused by external pressure compressing the fiber along its length. Any hardware along the cable path that can pinch or press on the fiber—panel doors, latches, or other hardware—can create these small bends. When the fiber experiences these micro-bends, light propagation is disturbed, which increases attenuation and can reduce bandwidth. That’s why this option is best: it recognizes all common pinch points, not just one specific source. If you only consider one item, you’d miss other places where the fiber could be pinched, such as latches or additional hardware, which are also capable of causing micro-bends. In practice, avoiding these issues involves routing away from pinch points, providing proper strain relief, and using protective sleeves or conduits.
