The Keysight AresONE 400GE is a high-performance network testing platform for 400 Gigabit Ethernet infrastructure validation across data centers, network equipment manufacturers, switch silicon developers, optical transceiver vendors, ASIC manufacturers, cloud service providers, and carriers. Available in 8-port and 16-port configurations, the 2U fixed chassis delivers up to 3.2 Tbps throughput per chassis, scaling to 51.2 Tbps for ASIC testing. The platform supports native 1x400GE per port via QSFP-DD interfaces with flexible multi-rate fan-out options: 2x200GE, 4x100GE, or 8x50GE per port. Multi-speed capability spans 10GE through 400GE on a single platform.
