SNIA

A standard for optical network elements and transmission.

SONET provides modular building blocks, fixed overheads, integrated operations channels, and flexible payload mappings. Basic SONET provides a data transfer capacity of 51.840 megabits/second. This is known as OC-1. Higher data transfer rates that are n times the basic rate are available (known as OC-n). OC-3, OC-12, OC-48, and OC-192 are currently in common use.
