Abstract

An important design problem for dense WDM optical networks is the placement of optical amplifiers along the transmission lines connecting optical add–drop multiplexers. We present a dynamic programming algorithm that chooses the minimum-cost amplifier placement subject to bounds on introduced nonlinear phase shift and noise. The algorithm is in current use and is effective over a wide range of design scenarios.
