Passive optical network (PON) is getting more popularity because it provides large bandwidth, uses only passive components that requires less power consumption, highly dynamic access network, and effectively converges several service providers. With the increase of multiple users having different priority classes of services an efficient access network is required which can handle the different data classes with better quality of services (QoSs). Usually, a single optical line terminal (OLT) and single wavelength (SS) PON is capable to provide multiple services and applications such as IPTV, HDTV, video conferencing, and real-time data transmission. However, the SS-PON is not the best network architecture to maintain better QoSs for all those services because it requires a complex dynamic bandwidth allocation (DBA) algorithm and synchronization of local time those lead a large delay. To overcome those …
