As AI workloads intensify and data centre architectures evolve, optical communications vendors are positioning co-packaged optics (CPO) and silicon photonics (SiPh) as core mid- to long-term growth markets. LuxNet expects 800G products to surpass 400G as the market mainstream in 2026, with 1.6T products entering initial shipments and supporting growth over the next two to three years. TrueLight is moving into the AI high-performance computing (HPC) supply chain via continuous-wave (CW) laser foundry services and expects the foundry revenue share in 2026 to exceed 2025 levels.
