1. Application Scenarios
Hyperscale Data Centers
Internet companies and cloud service providers (CSPs) are upgrading their data center network infrastructure from 100G to 400G to meet higher bandwidth demands and lower latency requirements.
Mainly used for core switching within data centers and Data Center Interconnect (DCI).
Cloud Computing and AI Clusters
AI and machine learning training require high-speed interconnects, especially for GPU server-to-server communication, such as NVIDIA DGX and Google TPU clusters.
The demand for high bandwidth and low latency in AI-driven data processing is driving the widespread adoption of 400G optical modules.
5G Transport Networks
400G optical modules are utilized in 5G front-haul and back-haul networks to support high-density data transmission and low-latency requirements, particularly in core and metro networks.
High-Performance Computing (HPC)
Scientific research, financial modeling, and genomic computing demand high-throughput, low-latency environments, promoting the adoption of 400G optical modules in supercomputing centers.
Enterprise Data Centers and Cloud Switching Enterprise data centers are upgrading their network architectures to support the growing demands of cloud storage, remote work, and big data analytics.
