Abstract

In this paper we investigate and quantify the dynamic behavior of the mode partition noise variance. We found that the mode partition noise variance is largest at the bit boundaries and depends on the slope (edge transition times) of the signal in links with one propagating fiber mode. In multimode fibers we show similar dependence, although the mode partition noise is reduced because fiber mode groups mix the chromatically dispersed laser modes responsible for mode partition noise.
