Abstract

A variety of passive optical network (PON) systems has been proposed to target the bottleneck problem in the local access. The medium access controls (MACs) of the PON systems are either based on cyclic rotation or polling mechanism. However, these MACs have inherited a potential problem; the cycle time (or polling cycle in the polling MACs) increases linearly as the number of attached ONUs scale up, which can be caused by increasing customer numbers. The longer cycle time means that the ONUs have to wait longer before the next transmission window arrives thus contributing to longer packet delays and poorer QoS. In this paper, a new WDM PON system is proposed where multiple wavelength channels are established in both upstream and downstream directions. The MAC applied is based on an adaptive polling mechanism, and can be used as an upgrade solution for PON systems
