FS Unveils 51.2T 400G and 800G AI Ethernet Switches Powered by Broadcom Tomahawk 5

New Castle, Delaware – FS, a trusted provider of ICT products and solutions, announced its latest 400G and 800G Ethernet switches designed for large AI clusters. Featuring the reliable Broadcom Tomahawk 5 chipset, these switches deliver up to 51.2 Tbps (102.4 Tbps Full Duplex) switching capacity and support lossless RoCEv2 networking, making them ideal for AI, big data, high-performance computing (HPC), and distributed storage.

As AI models grow increasingly complex and large-scale, traditional data center networks struggle to meet the demands of massive data transmission and processing. To address the challenges of AI/ML workloads, data centers require high-capacity systems in flat architectures to achieve low-latency, high-throughput data processing. FS introduced 400G and 800G AI switches with RoCE protocol support, significantly reducing latency and improving data transmission efficiency. This enables more efficient workflows for AI model training, large-scale parallel computing, and high-performance cloud applications.

The 400G switch features 128x QSFP112 ports, supporting line-rate forwarding. Each port can be configured as 100/200/400GbE, and with breakout cables, it supports 2x 200GbE or 4x 100GbE connections. Typical deployments support up to 8K 400G ports in Layer 2 networking and scale to 32K 400G ports in Layer 3 networking. The 800G model provides 64x OSFP ports. Each OSFP port can be configured as 400/800GbE. Additionally, it supports 2x 400GbE, 4x 200GbE, or 8x 100GbE via breakout cables.

Key Features of FS 400G and 800G AI Switches:

• Powered by Broadcom Tomahawk 5, delivering 51.2 Tbps (102.4 Tbps Full Duplex) of switching capacity.

• Supports lossless RoCEv2 networking for low-latency, zero-packet-loss transmission.

• High-density 100/200/400/800G port options in a compact 4 RU design.

• DLB and GLB load balancing technologies improve bandwidth efficiency and reduce AI training time.

• Adaptive routing minimizes congestion by selecting optimal paths based on real-time conditions.

• Ensures reliability with 2+2 hot-swappable power supplies and 7+1 smart fans.

Daniel Xiang, CEO of FS stated, "With the launch of our 400G and 800G AI switches, enterprises can leverage greater network capacity and efficiency for their AI clusters.
