SONET: Synchronous Optical Network

The Synchronous Optical Network (SONET), the US version of the standard published by the American National Standards Institutue (ANSI), is a set of standards for synchronous data transmission over fiber optic networks that are often used for framing and synchronization at the physical layer. SONET is based on transmission at speeds of multiples of 51.840 Mbps, or STS-1. SDH is the international version of the standard published by the International Telecommunications Union (ITU). Transmission rates of up to 10 Gbit/s can be achieved in today's SONET systems and the 40 Gbit/s systems are possible. SONET systems are fully compatiable to SDH systems.
