I. Market Status: AI Computing Power Revolution Spawns Explosive Demand

According to the analysis in Zhongyan Puhua Industry Research Institute's '2024-2029 In-depth Market Research and Investment Strategy Forecast Report on China's Optical Module Industry', the global optical module market size is expected to exceed 12.1 billion US dollars in 2025, with China's market size approaching 70 billion yuan and a compound annual growth rate (CAGR) of 13.4%. The core driver of this growth comes from the upgrading of computing power infrastructure brought by AI large model training and inference — a single AI server cluster requires thousands of 800G optical modules to achieve 10,000-card interconnection, which is like 'paving a wider track for the highway'.

The data center sector has become the main battlefield. In 2025, the global shipment of 800G optical modules will reach 19.9 million units, among which the procurement volume of Chinese cloud vendors will double year-on-year. Enterprises such as Alibaba Cloud and Tencent Cloud are accelerating the iteration from 400G to 800G.

Technological iteration presents the characteristic of 'rate leapfrog': 400G modules have just completed the replacement of 100G, 800G modules have occupied 32% of the data center market share, and 1.6T modules have started small-batch delivery. This speed is comparable to 'the leap from 4G to 5G in mobile phones', but the iteration cycle of optical modules is shorter. The commercialization progress of 1.6T modules in 2025 is a full year ahead of expectations.

II. Policy Interpretation: Dual-Drive of New Infrastructure and Autonomy

National policies shape the industry pattern from two dimensions:

1. Demand-Side Stimulus

The '14th Five-Year Plan for Digital Economy Development' requires gigabit fiber users to exceed 60 million by 2025, directly driving the demand for access network optical modules; the 'East Digital West Calculation' project promotes the application of 800G modules in cross-regional data center interconnection, with the relevant order scale exceeding 5 billion yuan in 2025.

2. Supply-Side Reform

The 'Action Plan for the Development of Basic Electronic Component Industry' clearly requires the localization rate of 25G and above optical chips to exceed 70% by 2025, forcing enterprises to break through technical bottlenecks. The yield rate of Huawei HiSilicon's self-developed 25G DFB chips has reached 85%, but high-end EML chips still rely on imports, with the import ratio remaining as high as 70% in 2025.

III. Market Pattern: Differentiation of Technical Routes and Global Layout

(I) Tripartite Balance of Power in Technical Routes

Silicon Photonics Technology: Infinera (China)'s 800G silicon photonics modules have achieved mass production, with costs 30% lower than traditional solutions. The penetration rate of silicon photonics modules will exceed 40% in 2025. Its 1.6T silicon photonics modules adopt 3D stacking technology, increasing port density by 4 times, which is like 'building a city on a fingernail'.

LPO (Linear Direct Drive) Technology: By removing the DSP chip, NeoPhotonics has reduced the power consumption of 800G modules by 50%, and has obtained orders from Meta and Amazon. The revenue share of LPO modules is expected to reach 15% in 2025.

CPO (Co-Packaged Optics) Technology: Enterprises such as ZTE have started layout, and trial commercialization is expected to start in 2026. This technology integrates the optical engine with the switching chip, which is like 'installing the engine and gearbox on the same base'.

(II) Strategic Differences Among Leading Enterprises

IV. Real Case Analysis: Technological Breakthroughs and Scenario Expansion

1. Infinera (China): From Follower to Rule-Maker

Its Thai factory adopts a non-US chip solution to avoid tariffs, with a monthly production capacity of 500,000 800G modules and a yield rate of 95%, far exceeding the industry average of 85%. More importantly, the company is deeply involved in the design of 1.6T modules for NVIDIA's GB200 servers, which is like 'customizing tracks for high-speed rail'.

2. NeoPhotonics: The 'Cost Killer' Nature of Its Thai Base

By reducing the cost of 800G modules to below $800 per unit, NeoPhotonics achieved a 'price butcher' style breakthrough in Amazon's orders. The power consumption advantage of its LPO modules in short-distance transmission scenarios is just like 'installing energy-saving air conditioners in data centers'.

3. Accelink Technologies: A Cross-Border Player from Communications to Industry

Its automotive LiDAR modules can withstand 5-2000Hz vibration and have passed rigorous tests by a new energy vehicle enterprise; in the industrial Internet field, 10G bidirectional single-fiber modules achieve microsecond-level real-time control, which is like 'installing nerve endings in factories'.

V. Forecast of Future Development Trends

Outlook from Zhongyan Puhua Industry Research Institute's '2024-2029 In-depth Market Research and Investment Strategy Forecast Report on China's Optical Module Industry':

1. Accelerated Technological Integration

In 2025, the combination of CPO and silicon photonics technology will become the focus. Infinera (China)'s 3.2T optical engine has entered the pilot test phase, targeting commercialization in 2030, which is equivalent to 'installing a turbocharger for optical modules'.

2. Fission of Application Scenarios

In the intelligent automotive field, 800G optical modules realize high-speed interconnection, and the value of optoelectronic components per vehicle will jump to 1,500 US dollars in 2025; single-photon detectors for quantum communication nodes have entered the engineering stage, with a bit error rate lower than 0.1%.

3. Globalization 2.0

Infinera (China) is building a factory in Mexico, and NeoPhotonics is laying out in Vietnam, avoiding geopolitical risks while being close to customer needs, which is like 'building factories at the customer's doorstep'.

In the future, optical modules will not only continue to serve as the 'blood vessels' of the digital economy, but also may become the 'nerves' of cutting-edge fields such as 6G and quantum communication, reshaping the way human society connects in a broader dimension.
