name: "Eoptolink" ticker: "300502:SZ" country: "China" layer: "04-Core Computing & Communication Hardware" sub_industry: "Optical Communications (Optical Modules)" core_business: "Researches and manufactures high-speed optical modules. As one of China's leading optical module companies, it has passed supply chain certifications from major North American cloud providers." moat: "Fast progress in 800G high-speed optical modules, successfully entering the supply chains of top North American cloud vendors, with strong cost control capabilities and a leading position in commercializing new technologies such as LPO (linear-drive pluggable optical modules)."
Company Overview
Founded in 2008 and headquartered in Chengdu, Sichuan, Eoptolink was listed on the Shenzhen Stock Exchange in 2016. The company is one of the core players in China's optical module industry, often referred to alongside Innolight as the "twin giants" of domestic optical modules.
Unlike Innolight's "broad and comprehensive" approach, Eoptolink is known for its speed—consistently staying ahead of the industry in the mass production ramp of each new generation of high-speed optical modules (100G→400G→800G). This rapid response capability has enabled Eoptolink to repeatedly outpace overseas competitors.
Core Business
High-Speed Optical Modules (800G / 400G) | Core Revenue
- 800G Optical Module Series: Both 800G products based on single-lane 100G and 200G technology have entered volume shipment, targeting leading North American cloud computing customers.
- 400G Optical Modules: Still the revenue mainstay, with steady shipment growth.
LPO (Linear-drive Pluggable Optical Modules)
LPO represents the next-generation frontier in optical module technology. By eliminating the traditional DSP chip, it reduces both power consumption and cost. Eoptolink is among the global leaders in commercializing LPO technology and has already sent samples to customers for validation.
Technology Moat
Customer Barrier: Eoptolink is one of the few Chinese optical module companies to pass full certification from major North American cloud providers (Amazon, Google, Meta). This certification process takes 1–2 years, forming a critical barrier to entering the high-end market.
Cost Advantage: Leveraging China's local supply chain and engineering talent dividend, Eoptolink maintains significantly lower manufacturing costs than overseas competitors such as Coherent.
