Core Viewpoint - The AI optical module market is experiencing unprecedented growth, with the total addressable market (TAM) expected to surge from $18 billion in 2025 to $50 billion by 2028, representing a threefold increase in three years [3][4]. Market Growth - The demand for high-end optical modules (800G and 1.6T) is projected to increase from 20 million units in 2025 to 80 million units by 2028, quadrupling in four years [4]. - Major cloud computing companies are expected to invest between $735 billion and $795 billion in capital expenditures this year, a 60% year-on-year increase, significantly contributing to data center construction and optical module demand [4]. CPO Technology - Co-Packaged Optics (CPO) integrates optical engines directly into switch chip packaging, offering benefits like faster transmission speeds and lower power consumption, but faces significant technical challenges [6][7]. - CPO's five major technical bottlenecks include low manufacturing yield, heat dissipation issues, high costs, an immature supply chain, and maintenance challenges [7][8]. Scenarios for CPO Impact - Morgan Stanley outlines three scenarios for CPO's impact on traditional optical modules: - **Base Case**: CPO achieves manufacturing breakthroughs by 2027, with minimal demand dilution for traditional modules (3% in 2026, 11% in 2027, 16% in 2028) [9][10]. - **Optimistic Case**: CPO's large-scale application is delayed beyond 2028, allowing traditional modules to maintain over 70% market share [10]. - **Pessimistic Case**: CPO achieves breakthroughs in late 2026, with demand dilution of 21% in 2026, 32% in 2027, and 38% in 2028, yet traditional modules still retain 79% market share [11]. NPO as a Response - Near Packaged Optics (NPO) serves as a middle ground for traditional optical module manufacturers, allowing them to enhance performance without the complexities of CPO [15][16]. Data Center Trends - Three major trends are reshaping data center architecture: Scale-out, Scale-up, and Scale-across, driving the demand for optical modules [17][18][19]. - Scale-out involves connecting multiple GPU racks, with high-end optical module demand expected to rise from 20 million units in 2025 to 53 million in 2026, a 166% increase [18]. - Scale-up focuses on GPU interconnects within racks, with significant opportunities arising as copper cables approach their physical limits [19]. - Scale-across addresses the need for interconnectivity between data centers, with traffic share increasing from 5% to 20%, necessitating high-speed optical modules [21]. OCS as a Growth Engine - Optical Circuit Switching (OCS) is creating new demand for optical modules, with a projected market size of $2 billion by 2030, complementing AI optical modules rather than competing with them [24][25]. Company Analysis - In the traditional optical module sector, Eoptolink and Coherent are expected to be the biggest winners, with significant price target increases reflecting their growth potential [27][28]. - Lumentum's stock has surged over 900% in the past year, but its valuation may be overly optimistic given the expected earnings growth [28]. - The CPO supply chain is beginning to take shape, with companies like TSMC and ASE positioning themselves to benefit from future CPO applications [31][32]. PCB and Connector Impacts - The rise of CPO presents a mixed bag for the PCB industry, with some companies facing structural headwinds while others, like Bizlink, stand to benefit from the transition to Active Electrical Cables (AEC) [37][38]. Cloud Vendor Attitudes - Major cloud vendors are actively pursuing CPO technology, indicating a serious commitment to its development, although large-scale applications remain in the pilot phase [41][43].

Investment Rating - The report maintains a "Buy" rating for key companies in the optical fiber and cable industry, including Zhongji Xuchuang, Xinyi Sheng, and Tianfu Communication, among others [11]. Core Insights - The optical fiber and cable industry is entering a new cycle driven by AI data centers and drone applications, with fiber prices having more than doubled since 2025, indicating a significant upturn in market conditions [1][20]. - The demand for optical fibers is shifting from traditional telecommunications to AI data centers, which require 5 to 10 times more fiber infrastructure than conventional cloud facilities. The share of AI fiber in global demand is expected to surge from 5% in 2024 to 30% by 2027 [3][25]. - Supply constraints are evident due to the long production cycle of optical fiber preform rods, which can take 18-24 months to expand capacity. This has led to a structural supply-demand mismatch, particularly affecting the G.652D fiber segment [4][23]. Summary by Sections Price Dynamics - Since late 2025, retail prices for optical fibers have been on the rise, with G.652.D bare fiber prices exceeding 30 yuan/km, and actual transaction prices often between 40-50 yuan/km, reflecting a cumulative increase of 94%-144% [2][21]. - The rising fiber prices have caused a disconnect between cable costs and operator bidding limits, leading to the suspension of collective procurement projects by operators like Guangdong Telecom [2][21]. Demand Drivers - The primary demand driver for this cycle is the construction of AI data centers, which significantly increases the demand for optical fibers. The consumption of fiber infrastructure by AI data centers is projected to be 5 to 10 times greater than that of traditional cloud facilities [3][25]. - The drone sector is also emerging as a new market for optical fibers, with current demand estimated at 50 million core kilometers per year, significantly increasing Russia's fiber consumption [3][25]. Supply Constraints - The production of optical fiber is constrained by the lengthy and technically challenging process of expanding preform rod capacity, which directly limits overall industry supply. New capacity from expansions initiated now will not be available until after 2027 [4][23]. - The focus on producing specialty fibers for AI applications is squeezing the capacity for standard G.652D fibers, leading to a supply gap in the general fiber market [4][23]. Investment Opportunities - The report highlights several companies as key investment opportunities within the optical fiber and cable sector, including Zhongji Xuchuang, Xinyi Sheng, and Tianfu Communication, as well as companies involved in the broader computing and cooling sectors [8][26].
