Definitions for "Synchronous Optical Network"
1. A new and growing body of standards that define all aspects of transporting and managing digital traffic over fiber-optic facilities in the public network. 2. (IRM) A network communication technology offering fiber optic transmission system for high-speed digital traffic.
Standards for transmitting digital information over optical networks. Fiber optic transmission rates range from 51.84 Mbps to 13.22 Gbps. It defines a physical interface, optical line rates known as Optical Carrier (OC) signals, frame formats and a OAM&P (Operations, Administration, Maintenance and Provisioning) protocol. The base rate is known as OC-1 and runs at 51.84 Mbps. Higher rates are a multiple of this such that OC-12 is equal to 622 Mbps (12 times 51.84 Mbps)
Fiber optic lines used for point-to-point high speed transmission of data using 51.8 Mbps as a central building block up to 2 Gbps.
