Celestica announced the DS6005 on October 12, 2026, positioning it as a high-capacity switch for next-generation AI data-center networks. The fully liquid-cooled system is rated for up to 102.4 Tbps and fits a 1.5OU form factor designed for OCP ORv3 deployments. 1
DS6005 specifications at a glance
Celestica lists the DS6005 as a 64-port switch, with each port rated at 1.6TbE, for a stated total capacity of 102.4 Tbps. The system uses Broadcom’s Tomahawk 6–Davisson switching silicon, according to the launch coverage. 10

| Feature | What the cited materials say |
|---|---|
| Switching capacity | Up to 102.4 Tbps |
| Ports | 64 × 1.6TbE, according to Celestica’s product page |
| Optics | Co-packaged optics, with optical engines integrated directly onto the switch ASIC |
| Cooling and form factor | Fully liquid-cooled, 1.5OU design for OCP ORv3 deployments |
| Switching silicon | Broadcom Tomahawk 6–Davisson |
What co-packaged optics changes
The DS6005 uses co-packaged optics (CPO): Celestica describes optical engines integrated directly onto the switch ASIC. That differs from a design using traditional plug-in optical modules, placing the optics alongside the switch chip instead. 10

Celestica presents the system as a response to the bandwidth-density and power demands of AI fabrics. Its announcement describes the 1.5OU, fully liquid-cooled system as designed to increase bandwidth density and reduce power in OCP ORv3 deployments. Those are stated design aims; the cited launch summary does not give a measured power-saving figure against pluggable optics. 1
What the announcement establishes—and what it doesn’t
The supported headline is a 102.4 Tbps, fully liquid-cooled CPO switch in a compact OCP ORv3 form factor. Celestica’s product page adds the 64-port, 1.6TbE configuration and direct optical-engine integration. 1

The cited announcement summary does not establish a quantified efficiency improvement or independently measured performance. It also does not substantiate further details such as ORv3-HPR compliance, an AMD Ryzen processor, external laser-module interfaces, or SONiC support. These should not be treated as confirmed specifications on the basis of the launch information cited here.
