OCP EMEA Summit 2026: Celestica Accelerates AI-Scale Networking with the DS6000-Series 1.6TbE Switch

Key Takeaways

• DS6000 series offers 64 ports of 1.6 TbE connectivity.
• Provides up to 102.4 Tbps non‑blocking switching capacity.
• Available in air‑cooled 3RU and hybrid‑cooled 2OU form factors.
• Built on Broadcom Tomahawk 6 silicon with SONiC support.
• Targets AI training clusters needing high‑density bandwidth.

Pulse Analysis

The surge in generative‑AI and large‑scale machine‑learning models has driven data‑center operators to seek ever‑higher network throughput. Traditional 400 GbE or 800 GbE fabrics are increasingly strained, prompting a shift toward 1.6 TbE solutions that can sustain petabyte‑scale data flows without congestion. By delivering 102.4 Tbps of non‑blocking capacity, Celestia's DS6000 series directly addresses this bottleneck, enabling AI clusters to scale both vertically and horizontally while preserving latency targets critical for model training and inference.

Technically, the DS6000 leverages Broadcom’s Tomahawk 6 (TH6) switch silicon, the industry’s most advanced high‑density ASIC. The platform supports both copper and optical 1.6 TbE OSFP224 interfaces, offering flexibility for diverse cooling and power budgets. Two form factors—air‑cooled 3RU for standard 19‑inch racks and hybrid‑cooled 2OU for OCP ORv3 racks—ensure compatibility across legacy and emerging data‑center designs. Integration with the open‑source SONiC operating system and compliance with OCP ESUN and UEC standards further simplify deployment, allowing operators to adopt a vendor‑agnostic stack while maintaining enterprise‑grade reliability.

Market implications are significant. By being among the first to ship TH6‑based 1.6 TbE switches, Celestica strengthens its foothold in the high‑speed networking segment, directly competing with incumbents like Cisco and Arista. The open‑networking approach aligns with the broader industry trend toward disaggregated infrastructure, giving hyperscalers and AI‑focused enterprises the agility to upgrade bandwidth without wholesale hardware replacement. As AI workloads continue to expand, the DS6000 series is poised to become a foundational component of next‑generation data‑center fabrics, driving both performance gains and cost efficiencies for customers worldwide.
