Abstract
This chapter addresses optical fiber systems and technologies for the access network. Access refers to the first mile network that connects subscribing customers to the network provider's outermost switching office. It addresses access networks optimized for the set of bidirectional interactive services usually offered to residential and small–to–medium businesses by the local exchange carrier (LEC). The chapter also illustrates the physical layer issues of optical access systems and components. A brief review of history of optical access network development and deployment and an overview of optical access architectures is also presented. The chapter concludes with current trends and possible future scenarios. It is noted that considerable creativity and thought is devoted to fiber in the access network, but the economics still do not work because the costs cannot be divided among a sufficient number of users. Digital Subscriber Line (DSL) is a successful access technology that is used for providing high-speed Internet over twisted pairs in the loop.
