Abstract: Multipath interference (MPI) poses a significant challenge for 4-level pulse amplitude modulation (PAM4) signals in short-reach intensity modulation and direct detection (IM/DD) interconnect systems. MPI, arising from signal reflections due to the multiple fiber connectors,… read more here.
