Synchronous Optical NetworkSynchronous optical networking (SONET) is a standardized digital communication protocol that is used to transfer digital bitstream over relatively long distances using a fiber optic. With SONET, multiple digital data streams are transferred at the same time over optical fiber using highly coherent light from light-emitting diodes (LEDs) and lasers.
SONET is a transport technology designed to provide enterprises and government users, as well as service providers with a network infrastructure with high survivability characteristics, so that business operations continue uninterrupted. SONET’s self-healing fiber optic ring functionality enables automatic network recovery due to failures that can be caused by a fiber optic cable cut, lost signal, or degraded signal (e.g. due to laser aging) or node/system failure.
SONET is also a technology that is designed to ensure network traffic is restored within 60 milliseconds in the event of a failure. SONET supports multiple data streams at a time. It was designed to provide efficient services in telecommunication systems and therefore became widely adopted. SONET uses standardized rates so that all kinds of organizations can be interconnected.
SONET is the North American standard for telecommunications transmission using fiber optic cables. SONET provides a set of protocols for the management and control of high bandwidth optical networking transmission.
