Abstract

In this paper, we introduce optimal and heuristic solutions for the scaled-up and denser version of sample metropolitan area network (MAN). The solution is based on placing hybrid optical amplifiers for high capacity dense wavelength division multiplexed (DWDM) links and by placing conventional optical amplifiers over local links with the goal of minimizing the total number of optical amplifiers needed in the network, hence reducing its cost. The optimal solution is formulated as a mixed integer linear program and genetic algorithm. It is observed that, using the optimized low cost hybrid Raman- erbium doped fiber amplifier (EDFA), the numbers of conventional optical amplifiers are reduced over back-bone high capacity link..
