Description: The passive optical network (PON) is an optical fiber based network architecture,which can provide much higher bandwidth in the access network compared to traditional copper-based networks. Incorporating wavelength-division multiplexing (WDM) in a PON allows one to support much higher bandwidth compared
to the standard PON, which operates in the “single-wavelength mode” where one wavelength is used for upstream transmission and a separate one is used for downstream transmission. We present a comprehensive review of various
aspects of WDM-PONs proposed in the literature. This includes enabling device technologies for WDM-PONs and network architectures, as well as the corresponding protocols and services that may be deployed on a WDM-PON.
The WDM-PON will become a revolutionary and scalable broadband access technology that will provide high bandwidth to end users. © 2005 Optical Society of America
