As AI workloads, high-performance computing (HPC), and cloud-native applications continue to grow exponentially, modern data centers are facing unprecedented east-west traffic demands. While 100G Ethernet once served as a robust backbone for hyperscale and enterprise networks, it is now reaching its limits. Bottlenecks in throughput, latency, and scalability have become increasingly common—particularly in environments with GPU clusters or distributed storage systems.
Yet, despite the emergence of 400G and even 800G technologies, many organizations are choosing 200G as their next upgrade step. Why? The answer lies not only in technical feasibility but also in economic and deployment logic. Understanding why 200G is becoming a strategic bridge between 100G and future-ready 400G is essential.
