Fiber optics in CATV networks

Fiber optics is playing an increasing role in transmission of CATV signals. This paper describes the currently evolving architectures which eliminate conventional coaxial trunks and make possible greatly expanded bandwidths. Evolving network architectures enable the extension of fiber deeper into the network structure while improving performance and reducing operating costs. Several different architectures will be examined and their advantages and disadvantages will be discussed as well as their ability to deliver different forms of entertainment video.
