FOA Lecture 22 Mode Power Distribution In Multimode Fibers

This is Lecture 22 in the FOA lecture series on multimode fibers. In this lecture we'll briefly review modes in graded-index multimode fibers then show how you can actually see the modes by using visible laser light from a VFL (visual fault locator.) Then we will show the effect of a mandrel wrap on the fiber, allowing you to actually see how the higher order modes are removed by the mandrel wrap.
