Abstract
A method for monitoring an optical network includes communicating optical traffic along a working path of an optical network. The optical network comprises a protection path for the optical traffic to communicate the optical traffic upon a failure in the working path. The protection path comprises two or more network elements coupled together by optical lines. The method also includes monitoring an idle signal of the protection path to detect an error in the protection path comprising an error in a component of one or more of the network elements.
