MDM seeks to replace wavelength division multiplexing (WDM) technology which is currently overwhelmed capacity-wise despite being regarded as a workhorse in networking. As a result, Elliptical Core Few Mode Fiber (EC-FMF) is used to converge specific modes which depend on the refractive index changes in the core to undergo a mode conversion process for switching.

Mode conversion is the method used through Beamprop by creating other channels to transmit data from one central mode. The resultant channels are numerically optimized using Matlab, and an elimination algorithm to remove unwanted channels. Therefore, the bandwidth capacities achieved were improved by 17% compared to current switch devices. This study achieved greater bandwidth capacity namely 40 Gbps for the 2 mode EC-FMF switch, 80 Gbps for the 4 mode EC-FMF switch and 120 Gbps for the 6 mode EC-FMF switch.
