This paper reviews our most recent results on mode-division multiplexing systems based on few-mode fibres with low differential mode delay, spanning from the fibre design optimization to receiver memory dimensioning. First, an optimized refractive-index profile for low differential mode delay and low macro-bend losses is presented. Afterwards, we present a semi-analytical model of the linear mode coupling induced by fibre imperfections and stress. Finally, the interplay between the linear mode coupling and the differential mode delay is studied numerically and analytically, allowing to quantify the receiver memory required for a given fibre span.
