800G and 1.6T optical interconnect is tracked as a supplier bottleneck across Physical AI, primarily within Connectivity, RF & Positioning and Edge Compute & Control Silicon. The current investment map connects it to 9 public stocks, including AAOI, ANET, AVGO.
800G and 1.6T optical interconnect: technology bottleneck and company exposure
800G and 1.6T optical interconnect is a deep technology investment theme inside Physical AI, connected to Connectivity, RF & Positioning, Edge Compute & Control Silicon. PXS Research tracks the public stocks supplying this bottleneck and links each company to its current research state.
What is the 800G and 1.6T optical interconnect bottleneck?
800G and 1.6T optical interconnect matters because Physical AI can scale only as quickly as its limiting infrastructure. Its role across Connectivity, RF & Positioning, Edge Compute & Control Silicon can constrain how reliably intelligence is trained, connected, sensed, manufactured or translated into movement.

The full 800G and 1.6T optical interconnect research brief is being built.
PXS Research has mapped this technology into Physical AI and the Connectivity, RF & Positioning · Edge Compute & Control Silicon layer, but the source note is not yet ready to publish as finished research. We are validating the engineering bottleneck, adoption evidence, investable supply chain and primary sources before assigning durable conviction.
Define the constraint
Explain the physics, engineering or regulatory bottleneck in plain language.
Validate adoption
Separate measurable deployment evidence from narrative and forecasts.
Map public exposure
Identify the public companies supplying the constraint and how directly they benefit.
Source the thesis
Attach primary filings, research papers and credible industry references.
