SONET & RESOURCES
Synchronous Optical NETwork
 Alliance Datacom is known around the networking industry as the "Network Protocol Resource Center." We have created an online reference center for all networking questions. If you have any questions concerning your wide area network solution or product selection, please contact our PROTOCOL TEAM for a fast quote or a networking solution.
The Synchronous Optical NETwork (SONET) standard for fiber optic networks was developed in the mid-1980's. It remains in widespread use today. In a nutshell, SONET allows multiple technologies and vendor products to interoperate by defining standard physical network interfaces.
SONET was originally designed for the public telephone network. In the early 1980's, the forced breakup of AT&T in the United States created numerous regional telephone companies, and these companies quickly encountered difficulties in networking with each other. Fiber optic cabling already prevailed for long distance voice traffic transmissions, but the existing networks proved unnecessarily expensive to build and difficult to extend for so-called long haul data and/or video traffic.
SONET commonly transmits data at speeds between 155 megabits per second (Mbps) and 2.5 gigabits per second (Gbps). To build these high-bandwidth data streams, SONET multiplexes together channels having bandwidth as low as 64 kilobits per second (Kpbs) into data frames sent at fixed intervals.
