Optical Communication - Optical Carrier Level                 Home : www.sharetechnote.com

 

 

A set of signaling rates designed for transmission over Synchronous Optical Network (SONET) networks. Optical carrier (OC-x) levels also apply to Asynchronous Transfer Mode (ATM) networks. The term “optical carrier” indicates that SONET runs over fiber-optic cabling. The following table shows some of the common OC-x transmission rates.
