Celestica Introduces New Family of 1.6TbE Data Center Switches to Power AI/ML Clusters

Rhea-AI Summary

Celestica (TSX: CLS / NYSE: CLS) introduced two 1.6TbE data center switches, the DS6000 (3RU) and DS6001 (2U hybrid-cooled), on October 10, 2025. Both use the Broadcom Tomahawk 6 chipset and deliver up to 102.4Tbps switching capacity via 64 x 1.6TbE OSFP ports, supporting 50/100/200/400/800GbE speeds and LPO/LRO optics. Celestica says the family doubles capacity versus its 800G solutions and will be contributed to the OCP community and listed on the OCP Marketplace with OCP Inspired recognition. The DS6001 targets 21-inch OCP ORv3 racks with hybrid air/liquid cooling for energy-optimized high-density deployments. Both switches support open-source NOS deployments (SONiC distributions) and will be shown at OCP Global Summit 2025.

Insights

Senior Networking Product Strategist

Celestica launched 1.6TbE switches (DS6000/DS6001) built on Broadcom TH6, doubling capacity versus prior 800G solutions.

These products deliver a clear technical step: two 64-port 1.6TbE designs offering up to 102.4Tbps switching capacity via the Broadcom Tomahawk 6 chipset. The DS6000 targets traditional air-cooled racks in a 3RU form factor while the DS6001 targets hybrid-cooled 21-inch OCP ORv3 racks in 2U. Both support flexible lane speeds (50/100/200/400/800GbE), OSFP ports, and an open NOS approach via SONiC distributions, positioning them for AI/ML cluster interconnects and OCP marketplace distribution.

Impact depends on adoption and ecosystem support. Key dependencies include customer validation of thermal and power characteristics for AI clusters, integration with customer NOS and optics (including LPO/LRO support), and real-world performance in scale-out topologies. The announcement cites vendor endorsement and OCP listing, which reduce adoption friction but do not guarantee procurement or broad deployment.

Watch for evidence of customer trials, volume design wins, and performance validations at the OCP Global Summit on October 13-16, 2025. Also monitor any published interoperability tests with third-party optics and NOS, and announcements of supply or volume shipment milestones over the next 6-12 months.

TORONTO, Oct. 10, 2025 (GLOBE NEWSWIRE) -- Celestica Inc. (TSX: CLS) (NYSE: CLS), a leader in design, manufacturing, supply chain and platform solutions for the world’s most innovative companies, today introduced two new 1.6TbE data center switches, the DS6000 and DS6001. These advanced switches are engineered to support high-bandwidth, AI/ML data center applications. Celestica plans to contribute the DS6000/DS6001 spec to the OCP Community and list them on the OCP Marketplace with the OCP Inspired™ recognition. 

The DS6000 is a 3RU, 64-port x 1.6TbE data center switch for traditional air-cooled data center installations. The DS6001 is a 2OU, 64-port x 1.6TbE switch offering a hybrid cooled solution based on the 21-inch OCP ORv3 rack.  Both switches are based on the new Broadcom Tomahawk 6 (TH6) switch chipset, providing up to 102.4Tbps of switching capacity. The DS6000 and DS6001 are the latest additions to the Celestica portfolio of high-performance data center switches and represent a doubling of switch capacity compared to Celestica’s existing, market-leading 800G solutions. They also offer a comprehensive set of AI routing features and interconnect options, designed to meet the demands of AI clusters.

"The introduction of our new 1.6T switches marks a significant milestone for Celestica and our customers. The DS6000 and DS6001 represent a new era in high-performance networking, doubling the switching capacity of our current offerings and designed specifically to meet the demands of AI/ML cluster applications,” says Gavin Cato, SVP & GM Portfolio Solutions & AI Platform Engineering, Celestica. “We're proud to showcase these innovations at OCP Global Summit, demonstrating our commitment to leading the open networking ecosystem."

The DS6000 offers several key advantages for data center customers seeking the highest performance:

• 102.4Tbps capacity with 224G SerDes lanes and support for LPO / LRO optics
• Performance through 64 x 1.6TbE OSFP ports
• Flexibility with 50/100/200/400/800GbE capable port speeds
• Reliability with redundant, field-replaceable fans and hot swappable power supplies
• Options for forward and reverse airflow configurations
  
  

The DS6001, while maintaining the same overall networking performance as the DS6000, is designed to operate in a hybrid cooling environment, leveraging a combination of air and liquid cooling techniques. The DS6001, taking up only 2U of rack density, is designed to operate in a 21-inch OCP ORv3 rack for maximum performance while optimizing energy efficiency and power utilization. 

As with all of Celestica’s switching solutions, both the DS6000 and DS6001 support an open-source Network Operating System (NOS) approach. This is achieved through the use of Celestica Solutions for SONiC and other SONiC distributions – open-source, validated and supported NOS that enable production-ready deployment in a multitude of use cases from the data center to the edge.

As important additions to Celestica’s open networking platforms, the DS6000 will be on display at the OCP Global Summit 2025 in San Jose, CA, October 13-16, in booth B2.
