104 Gbps PAM4 transmission over OM3 and OM4 fibers using 850 and 880 nm VCSELs

The receiver sensitivity of 52 Gbps-PAM4 is investigated over OM3/OM4 fibers in real time. The measured sensitivities are compared and correlated with measured fiber bandwidths for 850/880 nm channels to examine 104 Gbps SWDM2-PAM4 transmission.
