Definitions for "Bend Radius"
Constant Flexing: The minimum radius of a bend measured to the assembly's centerline to maximize assembly life and to be used in motion calculations. Static Bend: The radius of a bend measured to the assembly's centerline to which an assembly may be bent for installation. The assembly should be subjected to no further motion other than vibration.
The smallest bend a cable can withstand before the transmission is affected.
The minimum radius of curvature in which a fiber can bend without breakage, other adverse mechanical effects, or increased attenuation beyond an acceptable threshold.
