The Hybrid WDM/TDM PON, which combines Wavelength-division multiplexing (WDM) with TDM technology, is
presented as a promising solution for the next generation of optical access network. To realize the statistical multiplexing
of upstream wavelength resources, some optical tunable components are introduced in the optical network unit (ONU).
However, switch latency (SL) of these components is an important parameter that will constrain the performance of
Hybrid WDM/TDM PON. In this paper, we for the first time demonstrate and analyze the effect of channel switch
latency (SL) based on the extended WDM IPACT scheme via simulations. The simulation results show that the
performance such as delay, packet lost ratio, queue length and utilization will be constrained by SL, and the
WDM-IPACT-SL can adaptively adjust the channel switch time according to the different SL so as to reduce the
degeneration of the network performance in the practical applications of. Hybrid WDM/TDM PON
