A new paper of ours was published today in Optics Express (OPTICA Journal) on a possible solution for future optical access network (for FTTH and Fronthauling on PON above 50 Gbit/s per lambda and in particular on 200G PON). This is another paper from the research group of mine that focuses on physical layer solutions for Passive Optical Networks.
Title: "Analysis and experiments on C band 200G coherent PON based on Alamouti polarization-insensitive receivers"
