Passive Optical Network Evolution to Next Generation Passive Optical Network: A Review

The rapid expansion of Internet traffic shoves the communication networks to optical access networks for enhancing the transmission information rate. Passive optical network (PON) is a developed and most encouraging access network which provides the high bandwidth, information rate and low cost architecture for home and business enterprises. The main aim of this paper is to review the standardization evolution of PON to next generation passive optical network (NG-PON). Additionally, the literature review of PON and NG-PON based technologies are discussed. Also, it presents the possible challenges in NG-PON alongside their strengths and weakness in different techniques.
