Final answer:
Attenuation caused by external mechanisms that bend the optical fiber is known as bend loss. Bend loss occurs when the fiber is bent beyond its critical bending radius, causing the light to leak out of the fiber and result in signal loss.
Step-by-step explanation:
Attenuation caused by external mechanisms that bend the optical fiber is known as bend loss. Attenuation caused by external mechanisms that bend the optical fiber is known as bend loss. Bend loss occurs when the fiber is bent beyond its critical bending radius, causing the light to leak out of the fiber and result in signal loss.
Bend loss occurs when the fiber is bent beyond its critical bending radius, causing the light to leak out of the fiber and result in signal loss.
This phenomenon is specifically related to fiber optics in the field of physics. When light travels through a fiber, it undergoes total internal reflection to propagate along the fiber. However, if the fiber is bent too much, the light rays can escape, leading to attenuation.
