Network Optimization in the 600G Era


Data rates of 100G per wavelength once confined to the long-haul core portions of the network are now extending towards the edges of the network. Today, 600G per wavelength speeds are becoming available for use in the core as well as for data center interconnect (DCI) traffic enabled by the latest innovations in digital signal processing, optical, and mixed-signal component technologies. High modulation orders and high baud rates are now possible. These technologies also introduce advanced capabilities that allow the flexible fine-tuning of the optical transmission resulting in capacity optimization. Today’s coherent technology enables common optical hardware to achieve the high-performance finesse of a long-distance link, the sheer raw capacity for shorter DCI/edge links, and everything in between. This paper looks at long-haul, metro, and DCI/edge applications and how the Acacia AC1200 coherent modules provides benefits for each of these applications.
