Huawei targets AI optical networking with InP chip startup investment

What's the deal? HuaweiDealroom has a profile for this one. Try Dealroom → is investing in an indium phosphide (InP) optical chip startup as it pushes deeper into AI optical networking and silicon photonics. The move comes as surging AI data centre demand drives upgrades across global optical communications infrastructure.

Why now? The rapid buildout of AI data centres is straining existing networking capacity. Optical communications — the backbone connecting servers, GPUs, and clusters — need faster, more efficient chips to keep pace with the scale of AI workloads.

InP chips are critical components in high-speed optical transceivers, which convert electrical signals to light for data transmission. As data centres push toward 800G and 1.6T speeds, demand for advanced InP technology is accelerating.

What could go wrong? Huawei remains under sweeping US trade restrictions, which limit its access to advanced semiconductor manufacturing tools and certain chip technologies. Any tightening of export controls could constrain the startup's supply chain or Huawei's ability to scale the resulting products globally.

The InP chip market is also fiercely competitive, with established players in the US, Japan, and Europe already serving major cloud and telecom customers.

The signal: Huawei's move into optical chip supply chains underscores how AI infrastructure investment is spreading well beyond compute into the connective tissue of data centres. As a corporate investor, Huawei is vertically integrating at a moment when optical networking components are becoming a genuine bottleneck for AI cluster scaling — positioning itself to control a critical link in the chain that most hyperscalers still rely on third-party suppliers to provide.
