A method for powering up an optical network is provided. The method comprises remotely and safely increasing power to optical links in the optical network while monitoring signal levels in the network to discover installation errors, incorrect equipment configuration, and faulty components. In a modification to the method, attenuations of optical attenuators and gain values of optical amplifiers are set. The methods for powering up the optical network of the embodiments of the invention apply to both new optical networks and to new optical links added to pre-existing optical networks.

Method and system for powering up an optical network

A method and system for multi-level power management in an optical network is provided. They include three levels of power equalization. The first level of power management equalizes the powers of channels in a band of channels. The second level of power management equalizes the average powers of bands of channels on a fiber. The third level of control equalizes the powers of bands of channels on working and protection fibers for a path in the optical network. As a result, this multi-level power management in the network provides a dynamic, automatic method for the network to adjust to changing operating conditions and configurations and to maintain relatively stable network powers. Each level of power management may be implemented jointly or independently, and operates autonomously so that, for example, one modification comprises continuous first level control and only periodic second level control.
