Numerical simulation of helical structure mode-division multiplexing with nonconcentric ring vortices

Mode Division Multiplexing (MDM) increases aggregate capacity and improves spectral efficiency when used with wavelength division multiplexing (WDM). This paper numerically simulate the modal analysis and bit-error-rate (BER) evaluation of a new MDM architecture using concentric multi-diameter ring vortices in a multimode fibre (MMF) backbone. The study achieved a data rate of 40 Gbit/s for the MDM system on wavelength 1550.12 nm for a MMF...
