In 2026, the optical communication industry officially enters the 3.0 era. This is not a gradual upgrade, but an industrial paradigm revolution driven by the dual engines of AI computing power and 6G bearer networks. With the deep integration of communication, computing power, and sensing into a trinity, optical communication is leaping from a traditional transmission pipeline to the core hub of intelligent digital infrastructure in the AI era.
01 / Dual-Engine Drive: The Underlying Logic of Industrial Generational Transition
The basis for industrial generational transition has never been the linear improvement of technical parameters, but the fundamental shift in the underlying logic of demand.
The computing power engine is rewriting the underlying logic of network architecture. The scale of token invocations is advancing from the hundreds of billions to the hundreds of trillions. In 2026, the daily average scale of AI computing power tasks is expected to reach140 trillion times, with the computing power proportion for inference tasks rising to 60%. The exponential explosion of computing power demand is forcing the network to shift from "connection-driven" to "computing power-driven," making the all-optical architecture the only solution.
The connectivity engine, on the other hand, is reshaping the physical boundaries of the network. 2026 marks the crucial inaugural year for 6G standard formulation. The integrated networking of space, air, ground, and sea requires breaking through the geographical limitations of traditional terrestrial communication. Terrestrial macro stations and edge computing power nodes require high-density access of 50G/200G PON (Passive Optical Network), while low-earth orbit satellite networking demands ultra-low loss transmission of 100G inter-satellite links and 400G satellite-to-ground links.
The convergence of these two engines has given birth to the core definition of Optical Communication 3.0:
Driven by the dual engines of AI intelligent computing interconnection and 6G bearer networks, it achieves the deep integration of communication, computing power, and sensing into a trinity through technological leaps, propelling optical communication from a traditional transmission pipeline to the core hub of intelligent digital infrastructure in the AI era.
This is not a mere piling up of concepts, but a fundamental restructuring of industrial value positioning.
02 / The Tree of Product Ecosystem: Value Chain Restructuring Behind the Ten Leaps
The product ecosystem of Optical Communication 3.0 can be understood as a "tree." The root layer consists of core optical components and optical transmission media; the trunk layer comprises all-optical foundations, autonomous intelligent networks, and intelligent computing interconnection products; and the canopy layer features scenario integration innovations and trinity integrated solutions. From roots to canopy, the ten leap paths clearly outline the direction of value transfer in the industrial chain.
Breakthroughs at the underlying layer are the most critical. The iteration of optical chips, optical components, key materials, and process products consolidates the hardware foundation of Optical Communication 3.0. New optical fiber products such as hollow-core fibers and multi-core fibers break through the physical limits of traditional single-mode fibers. The speed iterates from 800G to 3.2T, and the product form evolves from pluggable to CPO (Co-Packaged Optics) / OIO (Optical I/O), reducing the power consumption of electrical links.
Mid-layer architecture upgrades determine efficiency. The coordinated optoelectronic scheduling of OTN (Optical Transport Network) / OXC (Optical Cross-Connect) / ROADM (Reconfigurable Optical Add-Drop Multiplexer) creates a deterministic high-speed network facing AI intelligent computing interconnection and 6G bearer networks. The network intelligent operation and maintenance product suite enables the evolution of O&M from manual to L5-level autonomous intelligence. Spaceborne laser terminals, spaceborne routing, ground terminals, and satellite-ground coordinated scheduling build an integrated space-ground solution.
Top-layer scenario integration creates increments. The integrated delivery solution of communication × sensing × computing power builds integrated computing power hub products for multiple industries. The quantum + OTN secure optical network solution and the multi-dimensional green and low-carbon complete product solutions covering components, parts, systems, and applications.
The core insight is: the leap in product paradigm signifies the restructuring of value distribution in the industrial chain. Each leap represents a profit transfer on the value chain. The opportunities, risks, and survival logic of enterprises at different positions change accordingly, bringing not only huge track dividends but also brand-new tests in technology routes, supply chains, and business models.
03 / Opportunities and Challenges: Two Sides of the Same Coin
On the opportunity side, technological leaps and market restructuring form a dual explosion.
Optical chip manufacturers face a window period for domestic substitution. Domestic enterprises are accelerating breakthroughs in areas such as 100G/200G EML (Electro-absorption Modulated Laser). In the next five years, the average annual growth rate of demand for core laser chips and components is expected to reach double-digit high growth. Optical module manufacturers are ushering in a simultaneous increase in volume and price. In 2026, the global demand for 800G optical modules is expected to exceed 40 million units, and by 2029, the shipment of 3.2T CPO ports is expected to surpass 10 million units. Optical fiber and cable manufacturers are shifting from product suppliers to full-scenario optical connection solution service providers for computing power clusters, with special optical fibers such as hollow-core and multi-core fibers opening up high-value-added incremental markets. System equipment manufacturers are accelerating the construction of computing power optical networks, and end-to-end integrated hardware and software solutions are ushering in a window period.
On the challenge side, three core focal points determine the success or failure of the breakthrough.
Supply chain game and imbalance: Upstream core optical chips such as high-end indium phosphide have long been monopolized by overseas giants. Downstream AI giants such as domestic and overseas BATZ and NVIDIA are independently developing optical hardware upwards, continuously squeezing the profits of external suppliers.
The "impossible triangle" of business models: In AI intelligent computing scenarios, the three demands of high performance, low cost, and fast delivery are difficult to balance simultaneously, and long-cycle fixed-price orders further exacerbate corporate operational pressure.
The "stark contrast" in talent supply and demand: Talent demand in frontier directions such as silicon photonics, CPO, NPO (Near-Package Optics), and CXL optical interconnects is exploding. There is a huge shortage of high-end composite talents, and traditional hardware R&D personnel urgently need to transform.
The "choice anxiety" in technology routes is particularly prominent. CPO represents the long-term ultimate direction, breaking through traditional interface bottlenecks to achieve ultimate power consumption and density optimization; NPO is the preferred choice for current implementation, balancing high performance and O&M convenience, and is recognized by authoritative institutions such as IPEC as the most implementable and cost-effective transition solution in the current computing power construction cycle; XPO represents the upgrade direction of pluggable solutions, achieving high integrated bandwidth density close to CPO while retaining hot-pluggable maintainability. During the window period when the three technology routes run in parallel, how to balance short-term commercial implementation and long-term technology layout is a strategic issue that all optical communication manufacturers need to think deeply about.
04 / Value Reshaping: From Lean Manufacturer to Optoelectronic Joint Innovation Architect
In the era of Optical Communication 3.0, the evolution path of enterprises is clearly discernible: lean manufacturers, system solution experts, and optoelectronic joint innovation architects.
The goal of lean manufacturers is to establish ultimate cost and quality advantages and consolidate the foundation of scaled manufacturing. The capabilities lie in building excellent supply chains, implementing lean production, strictly controlling quality standards, and scaled delivery systems. The challenge lies in the ease of falling into homogeneous price competition, where profit margins are easily squeezed.
The goal of system solution experts is to transcend single products and provide integrated solutions that deeply match scenarios. The capabilities lie in possessing deep scenario insights, hardware and software system integration, firmware development, and full-cycle consulting service capabilities. The challenge lies in huge R&D investments, high talent requirements, and a long return cycle for technology and market.
The goal of optoelectronic joint innovation architects is to participate in or even lead the definition of next-generation optoelectronic integrated architecture and the formulation of industry standards. The capabilities lie in possessing top-level architecture design vision, cutting-edge technology pre-research strength, interdisciplinary collaboration, and ecosystem building capabilities. The challenge lies in huge R&D investments, high uncertainty risks, and extremely high requirements for composite leading talents.
The industry does not require all enterprises to sprint to the third tier. Achieving excellence at the lean manufacturing and solution expert levels can also build solid differentiated barriers and obtain long-term commercial value. Optical Communication 3.0 is about layered symbiosis, not about everyone engaging in top-level architecture definition.
The competition paradigm has undergone a triple leap: the supply model shifts from batch supply of standardized hardware to customized solution delivery for AI computing power scenarios; the design paradigm shifts from independent device packaging to early collaborative definition with switching chips and GPUs; and the competition dimension shifts from competition in cost, yield rate, and delivery cycle to competition in technical standards, the right to define interface standards, and ecological discourse power.
Optical modules will not be replaced; instead, they will achieve value upgrades along with the evolution of the industrial chain, evolving into an indispensable midfield core of the computing power network. The moat for future optical communication enterprises lies not in what you produce, but in how you define the value of "connection" itself.
05 / The Way of Coopetition: Four-Dimensional Game and Six Major Actions
The global industrial macro pattern presents a four-dimensional game.
Policy window: The European Photonics Flagship is upgraded, with the EUR 400 million PIXEurope photonics pilot line seizing the commanding heights of optoelectronics; China's "Six Networks" construction sees an average annual investment of over CNY 7 trillion during the "15th Five-Year Plan" period, and a total investment of over CNY 4 trillion in the computing power network over five years.
Capital trend: Mergers and acquisitions accelerate, industry oligopolization intensifies, and the Matthew effect exacerbates. In March 2026, NVIDIA invested USD 2 billion each in Coherent and Lumentum, totaling USD 4 billion, directly locking in the capacity of indium phosphide wafers and advanced optical components. The regional restructuring of the supply chain proceeds in parallel with friend-shoring, strategic autonomy, and localized substitution.
Standard game: MSA (Multi-Source Agreement) becomes the main battlefield. OCI MSA focuses on the Scale-up optical interconnect ecosystem, Open CPX promotes NPO/CPO interoperability, XPO MSA focuses on high-density pluggable optical modules, and China's NPO MSA is initiated by over 20 enterprises including Huawei. The essence of the standard dispute is the dispute over pricing power in the next five years.
Structural contradiction in talent: Traditional optical communication talents focus on hardware, and there is a severe shortage of composite talents with "optics + electronics + computing + AI" skills. In 2026, the Wuhan East Lake High-Tech Development Zone launched the "AI Optical Doctor Plan," absorbing about 100 high-quality PhDs annually, reflecting the depth of the structural talent gap.
Behind the standard dispute is the dispute over technological discourse power, and behind the technological discourse power is the dispute over the density of capital and talent. In the next five years, the seating order of the global optical communication industry will be rearranged by the results of this "four-dimensional game."
The enterprise implementation action initiative proposes six major directions: standards first to master discourse power, technological breakthroughs for product breakthroughs, open collaboration for ecological win-win, resilient supply chain for a secure foundation, market exploration for dual circulation, and talent as the foundation for the intellectual engine.
06 / Practical Reflections Left for the Industry
The AIDC intelligent computing network industrial chain presents a four-layer structure: the top layer of AI computing power business and cloud intelligent management platforms, the middle layer of intelligent computing network systems and overall delivery, the basic layer of high-speed interconnection hardware clusters, and the root layer of core components and supporting services.
The practical propositions that the industry urgently needs to solve include: track selection—following the frontier or deeply cultivating segments? competitive breakthrough—facing large factories directly or differentiated positioning? technology routes—how to avoid blind following? ecological positioning—holding the ecological niche to achieve sustainability?
Optical Communication 3.0 is not only a technological leap but also the entrustment of the times.
2026-2027 is a window period for key technology iteration and industrial layout. Only by relying on collaborative innovation and layered gradient implementation across the entire industrial chain can we seize the ten-year industrial dividends driven by the dual wheels of AI and 6G.
Light has never been more important.
