Abstract

While further increasing the capacity of the SSMF is bounded by the nonlinear Shannon Limit, the annual traffic growth already exceeds the growth of the transmission capacity. In the nearest years, new traffic demands can only be accommodated by lighting a new fiber leading to a linear increase of the cost per bit. The development of communication systems based on multi-mode fibers is considered as a promising way for solving the above problem. However, there are new impairments that we have to be addressed: linear mode coupling, differential mode delay (DMD), and inter-mode nonlinear effects [1].
