Global optical module market is entering a super growth cycle fueled by AI computing power demands, transitioning from a period of stable expansion. Data shows the worldwide market size rose from 76.2 billion yuan in 2021 to 166.6 billion yuan in 2025, with projections exceeding 760 billion yuan by 2030, marking a more than tenfold increase over ten years. China has emerged as the top global demand market for optical modules, holding approximately 21% of the share, with its market size reaching 35 billion yuan in 2025 and expected to climb to 152 billion yuan by 2030. The core driver behind this sustained growth is the exponential need for high-speed data transmission bandwidth in AI large model training and inference clusters.
Global and Chinese Market Scale and Projections
Historical data indicates the global market stabilized between 76.2 billion and 81.6 billion yuan from 2021 to 2023. Starting in 2024, increasing demand for computing power accelerated growth, pushing the market to 110.8 billion yuan that year, and leaping to 166.6 billion yuan in 2025. Forecasts for 2026 through 2030 estimate sizes of 256.2 billion, 348.6 billion, 463.4 billion, 602.7 billion, and 760.2 billion yuan, respectively, showing a rising exponential curve. In parallel, the Chinese market expanded from 17.6 billion yuan in 2021 to 35 billion yuan in 2025, with projections reaching 56.4 billion, 76.7 billion, 97.3 billion, 120.5 billion, and 152 billion yuan for 2026 to 2030, a more than eightfold increase over the decade. By product category, the 2025 global market comprises 44.2 billion yuan for sub-400G, 52.2 billion yuan for 400G, 56.1 billion yuan for 600G, and 14.1 billion yuan for 1.6T modules. The 600G segment leads in volume, closely followed by 400G, together accounting for 65% of the total market. The 1.6T is still in small-scale trials, while 3.2T has not yet achieved commercial viability due to an immature ecosystem. Regionally, China leads with 21% market share, followed by Europe at 20% and North America at 18%, with these three regions collectively holding nearly 60% of the global market.
Competitive Landscape: Chinese Manufacturers Dominate Global Supply
Chinese manufacturers lead the global optical module market comprehensively. Zhongji Innolight holds the top global position, offering a full range of products from 10G to 1.6T, and maintains deep ties with major North American cloud providers, with 800G modules already in high-volume mass production. Eoptolink Technology ranks second globally, with over 90% of revenue coming from overseas markets, delivering 400G and 800G modules in bulk to international cloud firms and telecom operators, while advancing overseas manufacturing and long-haul coherent module development. Accelink Technologies is a rare domestic player with a complete in-house production line for optical chips, optical components, and optical modules, developing its own 25G/100G laser chips, and serves as a core supplier to China's three major telecom operators. Among foreign leaders, companies like Lumentum, Cisco, NeoPhotonics, and Acacia leverage self-developed high-end optical chips and long-term client relationships to maintain advantages in coherent long-haul transmission and silicon photonics integration, forming a complementary competitive dynamic with Chinese firms.
Industry Challenges and Growth Trends
The industry faces four key structural challenges: technology, capital, geopolitics, and talent. High-speed modules (600G, 1.6T, 3.2T) involve complex multidisciplinary processes like optoelectronic coupling and precision packaging. Production line construction and R&D require substantial capital, with rapid product iteration cycles. Risks persist from import restrictions on foreign high-end optical chips and testing equipment. There is also a shortage of talent with combined expertise in optics, electronics, and packaging. Four main trends are clear: product speed upgrades accelerate, with 800G widely deployed, 1.6T in volume delivery, and 3.2T samples completed, as cloud service providers secure long-term orders for capacity. New integration technologies like silicon photonics, Co-Packaged Optics (CPO), and Linear Pluggable Optics (LPO) are advancing, coexisting with traditional EML and coherent routes. Domestic substitution of upstream components deepens, shifting focus to optical chips and DSPs, with high-speed chips at 200G and above entering mass production faster, speeding up the formation of an autonomous supply chain. Market concentration among top players intensifies due to rising capital requirements for R&D and expansion, with the industry's CR5 increasing, allowing leading companies to integrate across the value chain, amplifying the Matthew effect.
The core conclusion of the report is that the global optical module market has entered a super growth cycle driven by AI computing power, with market size expected to exceed 250 billion yuan in 2026 and reach 760 billion yuan by 2030. China, as the top global demand market, is projected to hit 152 billion yuan by 2030. Short-term growth is driven by 800G proliferation and 1.6T commercialization, while medium- to long-term growth relies on increased silicon photonics penetration and the adoption of CPO and LPO technologies. Chinese manufacturers dominate global supply, with Zhongji Innolight and Eoptolink Technology ranking first and second globally. Industry entry barriers continue to rise, benefiting leading companies with complete supply chains, large-scale delivery capabilities, and technological reserves, as value further concentrates among top players. Key variables to monitor include progress in domestic high-end optical chip production, geopolitical supply chain risks, and the pace of technology iteration.
