Abstract

The demands on network capacity have grown significantly as the principal uses have expanded from simple character based terminal emulation and occasional file transfer to current efforts to provide real-time video and audio. In response to these demands, optic fiber is used increasingly in preference to copper cable. Optic fiber has the potential to carry considerably more data with less loss than copper cable. However, standards are needed to insure that various networks can communicate. This need is met by the Synchronous Optical Network (SONET) standard. SONET is used by telephone companies to provide both voice and data services, by cable television companies to provide interactive TV and by LANs as a base for high speed Asynchronous Transfer Mode (ATM) networks. This paper will explore how SONET works, how it is able to meet such diverse needs, its limitations and future potential and the differences from the highly similar Synchronous Digital Hierarchy (SDH) standard. As well as this the preference of TT on TTNET project will be commented.
