Broadcom, Cisco, and Ciena Put the Interconnect Stack in the Spotlight

Broadcom, Cisco, and Ciena are highlighting a fast-growing interconnect bottleneck as AI clusters push networking and optics into the critical path.

Updated

What is this trend?

AI infrastructure demand is pushing networking, optics, and interconnect components into the new bottleneck, making the fabric as strategic as compute and memory.

  • AI networking revenue and orders are surging as cluster scale strains the fabric.
  • Optical upgrades are now urgent for service providers trying to meet AI SLAs.
  • Interconnect TAM is expanding fast, with co-packaged optics emerging as a major growth area.
  • Supply leverage is shifting toward optics, HBM, and packaging vendors with scarce capacity.

What’s the latest?

Broadcom said AI networking revenue more than doubled year over year, Cisco reported networking product orders up 40% with $9.3 billion in cloud-provider orders tied to AI infrastructure, and Ciena’s
