Abstract
Traffic patterns in access networks have evolved from voice and text-oriented services to video and image-based services.This change can require new access networks which support high speed,symmetric and guaranteed bandwidths for future.To minimize the cost of implementing a FTTP solution,a Passive Optical Network(PON) that uses a point-to-multipoint architecture is generally considered to be the best approach.The principle of Time-Division Multiplexing(TDM)-PON and Wavelength-Division Multiplexing(WDM)-PON are discussed,which are the most promising candidates for practical future system.
