The increasing requirement of bandwidth has resulted in pushing the capacity of a single mode fiber by utilizing advanced modulation formats and polarization multiplexing. Shannon's channel capacity theorem extrapolated for including non-linearity in optical fiber puts an upper bound on the amount of data transmission a fiber can support at a given spectral efficiency. The use of space division multiplexing is considered to be the next big step towards the increase in bandwidth in long haul and access networks includes multi core and/or few mode fibers. In case of few mode fiber data to be transported is modulated in the fundamental and few higher order modes resulting in mode division multiplexing.This work aims at addressing the challenges involved in experimental demonstration, development of DSP algorithms to mitigate cross-talk and demonstration of enhancement of bandwidth in data transmission.
