Abstract

We review key aspects of analog coherent optics adoption in long haul datacenter regional networks. We discuss the main advantages and drawbacks of this approach and present potential improvements for next generation 60 + Gbaud long haul analog 8/16QAM systems. Finally, specificities of the 120 km datacenter interconnect (DCI) use case are also considered in the context of the ongoing OIF 400ZR standard effort.
