About Metro and Access Networks
Metro and access networks are a primary focus of next-generation network technology and architecture because carriers need to bring bandwidth-intensive content like video and enterprise applications to users without transporting it long distances, and increase the number of users with broadband connectivity. This topic section offers a wide range of resources on metro and access options, including fiber to the home (FTTH), DSL and cable architectures, to metropolitan area network topology including the migration from SONET to optical transport networks (OTNs).
