An interface standard for synchronous optical fiber transmission, applicable to the physical layer of the OSI (Open Systems Interconnection) reference model. SONET was developed by the Exchange Carriers Standards Association. SONET has a similar architecture to SDH (Synchronous Digital Hierarchy).

A standard for using optical media as the physical transport for high-speedlong-haul networks. SONET basic speeds start at 51.84 Mbps and go up to 2.5 Gbps
The American National Standards Institute standard for synchronous data transmission on optical media.

Bell telecommunication research institute in USA first proposed the synchronous optical network (SONET) hierarchy in 1984 .It consists of complete set of digital standards .The concept of SONET was accepted by CCITT in 1988 & renamed as “Synchronous digital hierarchy”
