Coherent optical OFDM: has its time come? [Invited]


There has been growing interest in coherent optical orthogonal frequencydivision multiplexing (CO-OFDM). We aim to present the case that the time for CO-OFDM has come, in terms of the demand from today’s ever-advancing optical networks and the availability of its underlying technologies. We first lay out the signal processing aspect for CO-OFDM and then… (More)
