Experimental demonstration of 51.56 Gbit/s PAM-4 at 905nm and impact of level dependent RIN

We demonstrate robust error-free transmission of 51.56 Gbit/s PAM-4 over multiple examples of 100m of multimode fiber with 905nm VCSELs. We further demonstrate the need to include level dependent RIN when assessing impairments and predicting performance of PAM-4 MMF links.
