What happened

Broadcom Inc. said it will showcase scale-up, scale-out, and scale-across AI networking products at the 2026 Open Compute Project (OCP) Global Summit in San Jose from October 12 to 15.S1 The lineup targets Open Rack Version 3 (ORV3) deployments and includes Ethernet switches, NICs, PCIe components, and integrated optics designed for high-bandwidth AI clusters.S1

Products slated for demonstration include the Tomahawk 6, Tomahawk Ultra, and Jericho 4 Ethernet switches, the Thor Ultra 800G and Thor 2 400G AI Ethernet NICs, and Broadcom's third-generation TH6-Davisson Co-Packaged Optics (CPO) portfolio, which the company describes as meeting the bandwidth needs of frontier AI models.S1 Charlie Kawwas, Ph.D., president of Broadcom's Semiconductor Solutions Group, framed Ethernet as the foundation that makes AI infrastructure growth sustainable.S1

Asad Khamisy, Ph.D., senior VP and GM of Broadcom's Core Switching Group, will deliver a keynote titled "Scaling AI Infrastructure Through Open Innovation" on Monday, October 12, 2026, at 5:30 p.m. Pacific Time in the South Hall of the San Jose Convention Center, covering modular rack designs aimed at clusters above 100,000 accelerators.S1 George Tchaparian, CEO of the Open Compute Project Foundation, called Broadcom a longstanding OCP contributor working on ORV3 racks, ORW wide racks, and new wide co-packaged optics.S1

Broadcom will also host technical sessions on 224G AECs, multi-path reliable connections, SRv6, SUE-T Ethernet transport, deep buffers, and CPO. The company said it will partner with more than 15 companies on the show floor, with named demos from Accton/Edgecore Networks, Alpha Networks, Celestica, Delta Electronics, and Micas Networks, all featuring Tomahawk 6 or TH6-Davisson 102.4T CPO hardware.S1

XAIPART take

Technical impact

The Tomahawk 6 family with third-generation TH6-Davisson CPO is the headline: a 102.4T switch with the optics engine co-packaged removes the pluggable-module bottleneck at 51.2T and above, where faceplate density and power become gating items for ORv3-era fabrics. XAIPART analysis Pairing that with Thor Ultra 800G NICs signals end-to-end 800G readiness for accelerators, while Jericho 4 plus MRC and SRv6 sessions point to multi-path routing that should reduce blast radius on a single NIC or switch failure. The 224G AEC tracks and ORW wide-rack demos address the longer-reach, copper-heavy back-of-rack cabling that hyperscalers currently constrain at 1.6T-class fabrics. XAIPART analysis

Market impact

Five named ODMs (Accton/Edgecore, Alpha Networks, Celestica, Delta, Micas) demoing the same Tomahawk 6 / TH6-Davisson silicon means CPO is moving out of single-vendor reference designs into a multi-ODM white-box supply chain, which is the path NVIDIA's NVLink and Marvell's networking silicon have already taken. XAIPART analysis For hyperscalers and large AI labs this broadens the merchant Ethernet option set against proprietary scale-up fabrics. For component buyers, multi-ODM availability typically compresses lead-time volatility once reference designs mature, although CPO remains a constrained specialty because laser sources and advanced packaging capacity are concentrated. XAIPART analysis

Action

Design engineers building ORv3-class fabrics should request TH6-Davisson 102.4T samples from at least two of the listed ODM partners to qualify a second source before locking the BOM for 2027 cluster rollouts. XAIPART analysis Procurement teams should treat Thor Ultra 800G and Tomahawk 6 placements as long-lead and pull forward forecasts to allow for the 224G AEC ecosystem to settle, and confirm with channel partners whether CPO modules carry separate warranty terms from the host switch. XAIPART analysis

XAIPART Forecast

XAIPART expects that by Q3 2027, at least two of the named ODM partners (Accton/Edgecore, Alpha Networks, Celestica, Delta, Micas) will publish general-availability pricing and lead times for a Tomahawk 6-Davisson 102.4T CPO switch in production volumes; if none of the five has moved the part to GA quoting by , this forecast is wrong.

Facts are as reported by the cited source. The design-in, sourcing and forward-looking statements above are XAIPART's analysis, not the source's claims. Unconfirmed: actual production lead times, GB/s-per-watt efficiency numbers, and any OEM design wins beyond the named show-floor partners.
