Current TDM-PON Technologies

Abstract

This chapter describes many aspects of time-division multiplexing-passive optical network (time-division multiplexing (TDM)-passive opticalnetwork (PON)) technology. TDM-PON is the architecture for optical access systems preferred by many network operators, due to its low operational and capital expenses. After the overview, topics related to the physical layer, such as burst-mode transmission and analog video distribution, are addressed. Then, topics in the higher layers of the network, such as the access control technologies, dynamic bandwidth allocation, security and privacy issues, protection switching and methods to improve energy efficiency like sleep modes, are described in detail for both ITU-T- and IEEE-based PONs. Finally, we conclude with a section on technologies beyond 10G PON.
