We evaluate how the joint selective introduction of improved hybrid amplification technologies at inline amplification sites and advanced digital signal processing (DSP) techniques at transceivers allows to greatly reduce the number of required optical-electro-optical (OEO) regenerators in transparent optical networks. We perform quantitative studies on two different topologies, focusing on two different DSP techniques: digital back-propagation and probabilistic shaping. Different Raman pumping levels are considered. OEOs saving up to 100% is demonstrated for both DSP techniques.

Abstract

We evaluate how the joint selective introduction of improved hybrid amplification technologies at inline amplification sites and advanced digital signal processing (DSP) techniques at transceivers allows to greatly reduce the number of required optical-electro-optical (OEO) regenerators in transparent optical networks. We perform quantitative studies on two different topologies, focusing on two different DSP techniques: digital back-propagation and probabilistic shaping. Different Raman pumping levels are considered. OEOs saving up to 100% is demonstrated for both DSP techniques.
