Inter‐ONU‐communication over different wavelength group in next generation pon based on physical‐layer network coding

An inter‐ONU‐communication (IOC) between different wavelength groups is proposed for next generation PON. The proposed IOC is based on physical‐layer network coding (PNC) to provide full‐duplex and private communications. The IOC requires no extra transmitter or receiver. 10‐Gb/s error‐free communications are experimentally demonstrated. © 2017 Wiley Periodicals, Inc. Microwave Opt Technol Lett 59:1068–1071, 2017
