How to Understand OC (Optical Carrier) Levels

SONET (Synchronous Optical Networking) is a standard for using optical fiber to communicate digital information including telephone and data traffic. The basic SONET service operates at OC1 (51.84 Mbits/second). OC is an acronym for Optical Carrier. OC levels are used to describe the various service levels used in SONET.

As of this writing (early 2005), the state of the art in SONET is OC192 (9953.28Mbits/second) which is 192 times faster than the basic SONET service of OC1. Higher OC levels have been designated to allow for future technological advances.
