Description: Intended for use in broadband ISDN and ATM networks, SONET (Synchronous Optical Network) and SDH (Synchronous Digital Hierarchy) have taken on a life of their own. As fiber optic cable becomes the standard for data transmission, telcos and other carriers are deploying more high-speed SONET/SDH technologies to support leased-line services such as DS-1 and DS-3. In search of ever-faster data speeds, leading corporations such as Boeing, AT & T, and Disney are moving their private global networks to a SONET / SDH infrastructure.
