NG-PON2 Network With 120Km Fiber Length Using Fiber Bragg Grating FBG

Next generation optical network are of great importance in face of the increasing number of subscribers and the increasing number of services provided by telecommunications companies around the world and the high quality of these services. Next generation optical network NG-PON2 which use TWDM technology are one of the latest standards set by the ITU-T organization and are especially used for FTTH applications to connect the fibers optic to the subscribers homes at the lowest cost and highest quality. This research examines the possibility of modifying the structure of ONU units for NG-PON2 using Fiber Bragg grating or what it is called FBG in order to increase the transport distance to 120km across single-mode optical fiber based on OptiSystem software, and comparing the final result of the research with the standard values of these system.
