Next Generations of Optical Access Networks - NG-PON and NG-ЕPON

The work is devoted to an overview of the development of standards for telecommunication access networks based on new generation passive optical network (PON) technologies. PON systems are the # 1 cable broadband solution. International bodies are actively standardizing new options for PON technologies. PON technologies are standardized by two international organizations: ITU and IEEE. New standards of these organizations allow to significantly increase network bandwidth and expand the application area of PON technologies. Considered the latest ITU standardized technology, NG-PON2. The progress of work carried out by the IEEE on the standardization of new technologies, namely, 25G-EPON, 50G-EPON and Super-PON, is considered. The main difficulty in the implementation of new generation systems is noted.
