Credo Technology Group has launched its new 800G HiWire ZeroFlap (ZF) Active Electrical Cables (AECs) designed for AI backend networks. These advanced AECs provide enhanced reach, zero soft link flaps, and support for lossless RDMA (Remote Direct Memory Access) networks that power AI clusters. With lengths up to 7 meters (22.97 feet), the cables are optimized for full host-to-switch connectivity in GPU-based supercomputing environments, benefiting from liquid cooling technology.
The 800G HiWire ZF AECs build on Credo’s successful HiWire AEC family, which has been widely adopted by hyperscalers. The new ZF series offers zero soft link flaps, addressing a critical need for stable and reliable connectivity in AI cluster deployments. The cables also deliver significant power and cost savings, offering up to 14W per link power reduction and $1,000 per GPU in savings when compared to legacy optical solutions.
The HiWire ZF family includes four key product offerings:
• 800G OSFP to OSFP
• 800G OSFP to OSFP-RHS
• 800G OSFP to 2*OSFP-RHS
• 800G OSFP to 2*Q112
“Cluster reliability is crucial when building the largest supercomputers with over 100,000 GPUs,” said Massine Merzouk, Network Engineer at X. “Credo’s HiWire AECs provide the stable transport platform we need for such massive systems.”
Key Points:
• 800G HiWire ZeroFlap AECs with zero soft link flaps.
• 7 m (22.97 ft) length, optimized for GPU clusters with liquid cooling.
• Reduces power by up to 14W per link and saves $1,000 per GPU.
• Four product variants available: OSFP to OSFP, OSFP to OSFP-RHS, OSFP to 2OSFP-RHS, OSFP to 2Q112.
