摘要

In wavelength-division multiplexing (WDM) ethernet passive optical networks (EPONs), to realize the statistical multiplexing of upstream wavelength resources, some optical tunable components are introduced in the optical network units.However, the switch latency (SL) of these tunable components constrains the performance of WDM-EPON.In this letter, we extend the mathematical model of the WDM interleaved polling with adaptive cycle time (IPACT) scheme by additionally considering the SL conditions.We also investigate the effect of channel SL on network performance.The simulation results show that the performance of WDM-IPACT-SL deteriorates as the SL increases.
