50Gbit/s PAM-4 MMF Transmission Using 1060nm VCSELs with Reach beyond 200m

We experimentally demonstrate error-free transmission of 50Gbit/s PAM-4 signals over OM3 and prototype wideband fiber using 1060nm VCSELs. FEC-conformed performance is demonstrated over 200m. An analytic model allows identification of penalties and demonstrates negligible MPN.
