Title:
APPARATUS AND METHODS FOR MITIGATING MULTIPATH INTERFERENCE IN FIBER TRANSMISSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/220054
Kind Code:
A3
Abstract:
An optical receiver that includes an input port configured to receive intensity modulated optical signal with multipath interference (MPI); a detector configured to convert the intensity modulated optical signal with multipath interference to an electrical signal; a high pass filter (HPF) configured to filter the electrical signal and suppress low frequency components induced by the MPI to produce a filtered electrical signal; and an output port configured to transmit the filtered electrical signal.
