In this paper, the first real time four 45 Gbps PAM4 transmission is demonstrated over SWDM4 grid using a PHY. We show that combination of PAM4, DSP and SWDM4 as well as wideband MMF potentially enables to double the previous achieved capacity and/or reach over a single MMF. In addition, successful transmission of four 45 Gbps PAM4 VCSEL based technology (four 22.5 Gbaud PAM4 optical channels without using multiplexer and de-multiplexer) is demonstrated over 100 and 200 m of conventional OM4 fibers as well as 100 m, 200 m, and 300 m of wideband OM4 fibers optimized for SWDM in the 850 nm to 950 nm wavelength range.
