Abstract

Power transience in an optical network hinders the performance of an optical communication system. In addition to increasing the capacity of the system, it has become mandatory to decrease fiber losses so as to increase the total efficiency of the system. Power transience is one such loss which not only decreases the efficiency of the system but also poses a threat to the functioning of active components. In this paper, we propose and exemplify the concept of recycling residual pumping in a Raman–erbium-doped fiber (EDF) hybrid optical amplifier (HOA) in the scenario of a dense wavelength division multiplexed (DWDM) system. Further, we investigated the power transience in the proposed hybrid amplifier and control it by using power shaping and channel shaping techniques.
