Design of Space Division Multiplexing with Six Polarized and Multiplexed Modes of PDM/DWDM System Using Multimode Splicer Enabling Gray mapping and MIMO Equilizer

The paper demonstrates design framework for few-mode fiber based space division multiplexing (SDM) transmission system. In this paper six polarized and multiplexed modes used to obtain ultra-high data rate. Polarization dual multiplexing (PDM) and dense wavelength multiplexing (DWDM) techniques are also used in this system to increase total system data rate. Different DSP techniques like MIMO equalizer will be used to mitigate multi-mode fiber losses like chromatic dispersion CD, deferential group delay DGD, inter symbol interference ISI, and polarization mode dispersion. The proposed system is tested under different cases to obtain the required performance. Gray mapping enabled in this system to decrease BER values for different LP modes.
