Passive optical network deployment in North America [Invited]

Feature Issue on Passive Optical Network Architectures and TechnologiesWe review the history of passive optical networking development and deployments in North America. The development of standards is discussed. We review early trials of passive optical network (PON) systems in North America, starting with A-PON, continuing with the current B-PON initiatives by Verizon and AT&T, and concluding with the initial view on G-PON emergence. Examples of how the fiber network is constructed in residential-focused B-PON deployments by AT&T and Verizon are shown. We provide several lessons learned. We conclude with a discussion of the various next-generation PON options under consideration in the industry forums and standards groups.
