Excerpt
Introduction: Optical network technologies are evolving rapidly in terms of functions and capabilities. The increasing importance of optical networks is evidenced by the copious amount of attention focused on IP over optical networks and related photonic and electronic interworking issues by all major network service providers, telecommunications equipment vendors, and standards organizations. In this regard, the term optical network is used generically in practice to refer to both SONET/SDH-based transport networks, as well as switched optical networks (including all-optical networks).
