Exercise 12

Let be the attenuation of the forward propagating light, s the attenuation of the backscattered light, and S the fraction of the total output power scattered in the backward direction, as described in Eq. (14.20). Show that the backscatter response of a rectangular pulse of width W from a point a distance L down the fiber is $Let be the attenuation of the forward propagating light, s the attenuation of the backscattered light, and S the fraction of the total output power scattered in the backward direction, as described in Eq. (14.20). Show that the backscatter response of a rectangular pulse of width W from a point a distance L down the fiber is when L W /2, and for 0 L W/2 Fig. 14.39 An OTDR trace of three 5-km spilced fibers$
