A method and apparatus are disclosed for terminating optical links in an optical network based on performance requirements. The present invention forces the termination of the received optical signals at each node only on the protection ring and does not force termination on the working ring, unless necessary to satisfy performance requirements. A signal on an end-to-end light path on the working ring is terminated only when required by engineering rules, such as signal-to-noise requirements. Specifically, the present invention does not force terminate an end-to-end light path on the working ring at a given node (or on a link between two nodes) unless the signal will fail to meet certain criteria, such as a minimum optical signal-to-noise ratio, at the next node.
