From 400G to 1600G - Cloud Scale Deployment and Intelligent Operation of Inter-Data Center Coherent Links

This paper discusses the transition from 400ZR to 1600ZR technology, emphasizing the need for robust forward error correction (FEC) mechanisms to maintain performance margins. The paper also explores intelligent operation using automated tools and AI to handle link failures, ensuring seamless data transfer and network reliability. The findings highlight the significance of 1600ZR technology in meeting the bandwidth demand and enabling next-generation AI-driven applications.
