When designing optical fibers for telecommunications engineers try to avoid light "bouncing around" inside the fiber because it causes loss in amplitude of the signal beig transmitted down the fiber. Leave it to my homies at my Alma Mater to come up with a way to turn loss into gain.....again.
Fiber manufacturers have to keep in mind the use of CWDM and DWDM(multiple light wavelengths over a single strand of fiber) when constructing fiber cables. They can’t have lightwaves “bouncing around” inside fiber and have it work.
