Innolight
Designs and manufactures high-speed optical modules, solving the high-speed data transmission bottleneck between GPUs inside AI clusters in data centers.
Globally leading in 800G and 1.6T high-speed optical module technology with the largest production capacity; deeply tied to NVIDIA and North American cloud giants' supply chains. Strong silicon photonics technology reserves.
High-Speed Optical Modules (800G / 1.6T) | Core Revenue (Accounts for >80% of Revenue)
- 800G Optical Modules: The flagship product for current AI data centers, with a per-module transmission rate of 800Gbps, used to connect GPU servers to switches. Innolight holds more than 40% of the global 800G optical module market, ranking first.
- 1.6T Optical Modules: The next-generation product, expected to ramp in 2025-2026. NVIDIA's next-generation GPU clusters will adopt 1.6T optical modules at scale. Innolight has already delivered samples and passed validation.
- Silicon Photonics: Innolight has made deep technical investments in Silicon Photonics. Silicon photonic modules offer significant advantages in power consumption and cost, and are expected to become the mainstream solution in the 1.6T era.
Optical Devices & Components
Innolight self-develops Transmitter Optical Sub-Assemblies (TOSA) and Receiver Optical Sub-Assemblies (ROSA), covering the complete optical link from chip level to module level, further reducing costs and securing supply chain stability.
Technology Moat
Scale & Delivery Capability: Innolight can deliver high-end optical modules at a speed and scale unmatched by competitors. This mass production capability is built upon proprietary automated production lines and deep collaboration with upstream optical chip suppliers.
Deep Upstream/Downstream Integration: Upstream, Innolight has established close supply relationships with optical chip giants (such as Lumentum and Coherent) to ensure a stable supply of core optical components; downstream, it is deeply locked into major North American customers including NVIDIA, Google, Amazon, and Meta.
Leading Technology Iteration: The company completes a new product generation every 2-3 years (400G→800G→1.6T), consistently maintaining the first-mover shipping advantage.

Risks & Summary
Key Risks:
- Global trade tensions may impact Innolight's supply to major North American customers.
- The optical module industry is highly competitive, with peers such as Eoptolink catching up rapidly.
- Risk of cyclical fluctuations in downstream demand.
Core Industry Value: Innolight is a rare global leader from China in the AI hardware supply chain. Unlike fields such as GPU and HBM, where most Chinese companies are in a catch-up role, optical modules are a track where Chinese companies have already achieved global leadership. Innolight's growth directly reflects the health of global AI compute investment.
