Calnex Solutions Introduces 400G Ethernet Emulation for AI Infrastructure Testing
Calnex Solutions has achieved 400G Ethernet validation for AI infrastructures, enabling engineers to test lossless Ethernet fabrics with full throughput and controlled impairments. This advancement is crucial for optimizing GPU utilization and validating network performance in large-scale AI applications.

Calnex Solutions plc has demonstrated 400G Ethernet validation at full line rate, achieving 100 percent throughput while allowing Priority Flow Control (PFC) frames to pass transparently. This capability enables effective testing of lossless Ethernet fabrics under controlled lab conditions, addressing challenges like microbursts and congestion that can impact GPU utilization.
By simulating real-world network conditions, engineering teams can validate performance more reliably. This development reinforces Calnex's position in AI validation and supports various applications in AI and data center networking as demand for infrastructure testing grows.
