Versatile MDM-OFDM system with selectable single-mode half-subcarrier or two-mode full-subcarrier multiplexing

Year: 2024

Type: article

Abstract: We propose a novel all-optical hybrid MDM-OFDM system with variable transmission capacity by switching between two-mode full subcarriers and single-mode sparse subcarriers multiplexing, using power loading. Analytical results indicate that in the two-mode full subcarrier multiplexing, a 0.26 dB power loading for the TE10 mode ensures uniform performances for all subcarriers. Additionally, by suppressing the TE10 mode with a 12 dB power load, similar characteristics and functionality to single-mode sparse subcarrier multiplexing with only the TE00 mode can be achieved. The system provides variable transmission rates using an all-optical processing, without varying the modulation scheme and the symbol rate.
