ABSTRACT:
A method for determining locations and gain settings of optical amplifiers in an optical network is provided. The method comprises evaluating allowable amplifier locations and successively eliminating selected locations until no further locations can be eliminated without the network violating predetermined specifications. This systematic method is applicable to a variety of network topologies and takes into account existing network limitations. In one embodiment, the method for determining the locations and gain settings of the amplifiers uses the amount of operating margin in the network to select locations to be eliminated. In another embodiment, the method is repeated a number of times with different selections of amplifier locations, and the method providing the arrangement with the least number of amplifiers is chosen.
