Abstract:
1. A method for planning a network configuration in an optical network using an electronic processing device, the method comprising: in the electronic processing device, determining candidate locations for placing pre- or post-amplifiers along spans of the optical network as a function of loss in each span, expected traffic patterns, and proposed regeneration locations along paths of expected traffic; in the electronic processing device, determining regeneration locations for placing regenerator modules based on the candidate locations; in the electronic processing device, determining a plurality of costs for maintaining signal strength in a corresponding plurality of network configurations stored by the electronic processing device, the network configurations including (i) a configuration of regenerators, (ii) a configuration of pre- or post-amplifiers and no regenerators, and (iii) a configuration of pre- and post-amplifiers in the candidate locations and regenerator modules in the regeneration locations determined; and in the electronic processing device, selecting a configuration from among the plurality of network configurations stored as a function of the plurality of costs determined.
