In terms of bend radius and tension, how do dynamic and static differ?

• A. Dynamic Bend Radius applies during movement, Static Bend Radius applies to stored configuration
• B. Dynamic Bend Radius is larger than Static Bend Radius
• C. Dynamic Bend Radius and Static Bend Radius are identical
• D. Static Bend Radius applies during movement, Dynamic Bend Radius applies to stored configuration

Answer: (A)

Bend radius and tension are defined for the state the fiber is in. Dynamic bend radius is the constraint you use when the fiber is moving or under changing forces, because motion adds varying tension, accelerations, and vibrations that can tighten or loosen bends. The goal is to keep those bends gentle so losses and mechanical stress don’t spike during operation. Static bend radius, by contrast, is the constraint for when the fiber is fixed in place or stored in a configuration; it protects against long-term deformation and microbends from a fixed layout. That’s why the correct statement is that dynamic bend radius applies during movement, while static bend radius applies to stored configuration. The other ideas aren’t accurate because they imply a simple size relationship, claim they’re the same, or invert the definitions. Understanding this distinction helps ensure the fiber stays within safe limits both when it’s in use and when it’s laid out in a fixed route.
