Q.

In the given equation, state what αr suggests?

A. radius of curvature
B. refractive index difference
C. radiation attenuation coefficients
D. constant of proportionality
Answer» C. radiation attenuation coefficients
Explanation: above equation represents the fiber loss. this loss is seen at bends and curves as the fibers suffer radiation losses at curves. these radiation losses are represented by a radiation attenuation coefficient (αr).
