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

Abstract

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.
