Abstract :
We propose an optimization on the amplifier placement to enhance the energy efficiency of the future optical transport networks based on WDM with mixed line rate transmissions. Simulation results show significant energy efficiency per GHz improvements of up to 74% thanks to the deployment of additional amplifiers, allowing for the utilization of more energy and spectral efficient modulation formats.
