Synchronous Optical NETwork

(pronounced: son-net)

A family of fiber-optic transmission rates initiated by Bellcore so that the RBOCs could create an infrastructure for new broadband services. SONET was created to provide the flexibility needed to transport many digital signals with many different capacities, and to provide a standard for manufacturers as the use of broadband transmission increases. The transmission rates are from 51.84 Mbps to 13.22 Gbps.
