Siemon's 800G-capable direct attach copper cable assembly

The Siemon Company recently announced a portfolio of direct attach copper (DAC) and active copper cable (ACC/AEC) assemblies for high-speed switch-to-switch and switch-to-server/storage applications. “Supporting Ethernet and InfiniBand at speeds up to 800G, these cables are designed to optimize performance and simplify cable management in today’s demanding data center environments,” the company said when announcing the portfolio.

“The key to successful high-density deployments lies in the flexibility and reliability of your cabling infrastructure,” commented Ryan Harris, The Siemon Company’s director of sales engineering. “Traditional coper cables simply weren’t designed for the tight spaces and complex routing of today’s high-speed server deployments.”

The 200G, 400G, and 800G DAC and ACC assemblies in the newly introduced portfolio “demonstrate the company’s commitment to high performance, reliability, and best-in-class cable management,” the company added. “These assemblies are rigorously tested for interoperability, performance, and signal quality at PAM 4 speeds and are compatible with OSFP, QSFP-DD, QSFP, SFP-DD, and SFP-12 connectors. This new generation of DAC and active copper cables represents a significant leap forward in cable design. They enable low-power, low-latency copper cable deployments at next-generation 800G network speeds. With a smaller bend radius and 40% smaller cable diameter compared to traditional jacketed cable, Siemon is simplifying 800G deployments.”
