TORONTO, Oct. 10, 2025 (GLOBE NEWSWIRE) -- Celestica Inc. ( 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 ( CLS ) 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 ( CLS ) 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 ( CLS ) 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 ( CLS ). “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 opticsPerformance through 64 x 1.6TbE OSFP portsFlexibility with 50/100/200/400/800GbE capable port speedsReliability with redundant, field-replaceable fans and hot swappable power suppliesOptions 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.
