CONFIRMED by Celestica’s press release and product page of 12 October 2026. Power, latency and reliability gains are what the switch is “designed to” deliver, per Celestica; no figures, price or ship date were given.
Celestica has introduced the DS6005, a data centre switch for AI networks that puts the optics in the same package as the switch chip [1][2].
What it is
Most network switches use pluggable optical modules in the front panel to turn electrical signals into light. In the DS6005, Celestica co-packages the optical engines with the switch chip, which it says removes the need for those front-panel modules [1]. This is called co-packaged optics (CPO).
Key specifications
- Capacity: up to 102.4Tbps, built on the Broadcom Tomahawk 6 – Davisson switch chip [1]
- Ports: 64 x 1.6TbE [1][2]
- Size: 1.5OU, for OCP ORv3 racks [1]
- Cooling: fully liquid-cooled [1]
- Lasers: field-replaceable external laser modules [1]
- Software: SONiC support [1]. SONiC is open-source network software.
Celestica says the design is meant to help operators improve bandwidth density, reduce latency and improve power efficiency [1]. It did not publish power or latency figures, a price or a ship date. Celestica is showing the DS6005 at the OCP Global Summit, 12-15 October 2026 [1].
Analyst view
“AI networking is shifting the constraint from compute to the physical infrastructure around it, where power, density, reach, and deployment complexity increasingly matter. Co-packaged optics is one of the industry’s important paths to address these challenges, while pluggable, near-package, and co-packaged approaches will continue to coexist as the ecosystem matures. Celestica’s DS6005 is a meaningful example of how the industry is beginning to apply CPO to high-density AI networking, giving operators another option as they scale AI fabrics,” said Sameh Boujelbene, Vice President of Research at Dell’Oro Group [1].
