Summary:Vulnerability of an optical network to channel impairments or the like, is addressed by utilizing real-time monitoring and control of one or more prescribed optical channel impairments. The one or more impairments are compensated for by employing an optimization process in the optical network such that the optical signals from the source or sources of the impairments are controllably adjusted at any particular node in the network. In a specific embodiment of the invention, the optical signals are attenuated more or less at the source node of the associated optical channel, e.g., wavelength », in order to optimize performance (100) of the corresponding optical channel in the network. This is realized by employing a variable optical attenuator at the » laser source of optical channel having the impairment.
