Exercise 20

Consider two multimode graded-index fibers that have the characteristics given in Table P5.16. If these two fibers are perfectly aligned with no gap between them, calculate the splice losses and the coupling efficiencies for the following cases:
( a ) Light going from fiber 1 to fiber 2.
( b ) Light going from fiber 2 to fiber 1.
