A core data center in East China undertakes high-concurrency businesses such as finance and cloud services. With the advancement of the "East Data West Computing" strategy, data volume increases by 60% annually. The original 200G modules cannot support the daily average 15PB cross-cabinet transmission demand, and a 400G upgrade solution is urgently needed, which balances stability and green energy conservation.

At the critical stage of large-scale 5G network deployment, a major mainstream operator faces three key upgrade challenges: bandwidth bottlenecks, excessive latency, and insufficient compatibility.

A municipal government network covers over 200 departments and 12 million citizens, handling core services such as administrative approvals and public services. With the deepening of the "One-Stop Government Service" platform, data exchange volume has increased by 45% annually, highlighting the bottleneck of the existing 10G equipment and necessitating a 100G solution. The client's core requirements focus on low-cost deployment, rapid launch, and energy efficiency, while also mitigating interference from the complex electromagnetic environment of the government data center.

A leading AI company's computing center deploys thousands of GPU servers using a leaf-spine network architecture to support trillions of parameters in large-scale model training and intelligent inference, with a daily cross-node data exchange volume exceeding 60PB. There is an urgent need for short-range direct connections between GPU clusters, servers, and switches. However, the existing 200G solution suffers from a mismatch between "strong computing power and weak bandwidth," necessitating the use of 400G OSFP112 VR4 short-range high-density interconnect modules to overcome the transmission bottleneck while also ensuring energy efficiency and rapid deployment.
