Abstract
The present invention addresses the need for optical transmission systems, apparatuses, and methods having increased flexibility and reliability. Optical systems of the present invention are configured to provide alarms, provision, and/or perform protection switching, if the number of corrected errors exceeds a threshold criteria. Various system parameters, in addition to protection thresholds, can be adjusted based on the relationship between the number of one errors, zero errors, and/or total errors being corrected in the system.
