Abstract:
A method for use in an optical transmission system for optimizing optical channel performance comprising the steps of:(a) selecting a received prescribed optical channel having a prescribed optical wavelength; (b) a first step of evaluating a predetermined transmission performance metric of said selected prescribed optical channel; (c) a first step of determining if said prescribed metric under evaluation is within acceptable criteria; (d) if not, generating a first control message to adjust at least a first controllable optical power adjustment unit associated with said selected prescribed optical channel; (e) supplying said first control message to cause said first controllable power adjustment unit to adjust in such a manner as to optimize said prescribed metric of said selected prescribed optical channel; (f) a second step of evaluating said predetermined transmission performance metric of said selected optical channel; (g) a second step of determining if said prescribed metric under evaluation is within acceptable criteria, and (h) if not, repeating steps (d) through (h) until said prescribed metric is within acceptable criteria; (i) determining if said selected prescribed optical channel having been optimized is the last of said one or more optical channels and, if not, (i) selecting another prescribed optical channel having another prescribed optical wavelength; and repeating steps (b) through (i) until step (h) indicates that the last one of said selected prescribed optical channels has been optimized.
