Industry Insights | OSIC 2026: The Dawn of the Optical Communication 3.0 Era!

At the recently concluded 3rd AI + Optoelectronic Intelligent Networking Conference (OSIC 2026), ICC Xunshi Industry Institute officially proposed and defined the "3.0 Era" of optical communications. The optical communications industry has moved beyond a simple bandwidth expansion cycle into a new, integrated phase driven by AI computing power and 6G, unifying communication, computing, and sensing.

I. Three Generations of Iteration: Optical Communication Achieves Comprehensive Industry Value Upgrade

ICC's Chief Expert Wu Jun delivered a keynote speech outlining the evolution of the three generations of the optical communications industry.

Optical Communication Era 1.0: Solving "Connectivity"With fiber-optic transmission as the foundation, we have established the core communication network infrastructure. The primary goal is to achieve comprehensive and accessible network connectivity, laying the groundwork for global digital communications.

Optical Communication 2.0 Era – Solving "How Fast"Focus on bandwidth and rate expansion, continuously upgrade transmission pipeline performance to meet data transfer needs in the era of mobile internet and cloud computing.

Optical Communication 3.0 Era – Solving "Strength and Intelligence"Driven by AI computing power networking and 6G all-domain coverage, we transcend the traditional "transport pipe" role to become the core infrastructure for the AI-driven digital economy and integrated air-space-sea networks, achieving seamless fusion of communication, computing, and sensing.

II. Why the "3.0 Era" Is Being Introduced Now

With the explosion of the AI industry and the launch of 6G standardization, traditional optical communication systems can no longer meet new industrial demands, becoming a core driver to usher in the 3.0 era of optical communications.

In terms of AI computing powerAccelerated large model iteration and widespread AI Agent adoption have made 10,000-to-100,000-card computing clusters the industry standard. With data center rack power consumption soaring, copper cabling can no longer meet demands; high-speed, low-power, and highly stable optical interconnects have become the core solution for cluster connectivity. Meanwhile, inference workloads impose extreme requirements on optical networks for ultra-low latency, intelligence, and elasticity.

In the dimension of 6G developmentIn 2026, the 6G standard officially launched, with integrated air-space-sea communication and converged communication-sensing-computing scenarios deployed. This demands that optical networks provide P-level bandwidth, microsecond-level latency, and ultra-low energy consumption for ubiquitous connectivity, driving a comprehensive technological upgrade and architectural restructuring in optical communications.

III. Ten Technological Leaps Redefining New Industrial Technology Roadmaps

OSIC 2026 Officially Releases the Top 10 Breakthrough Directions in Optical Communication, Spanning the Entire Optoelectronic Industry Chain and Serving as the Core Strategic Blueprint for R&D, Product Iteration, and Industry Deployment Over the Next Five Years.

respectivelyChip breakthrough, module upgrade, medium revitalization, compute-network access, intelligent computing interconnection, all-optical foundation, autonomous network, space-ground integration, secure and green, unified communication-sensing-computingTen key directions to comprehensively upgrade the entire chain—from chips and modules to fiber optics, networks, and applications.

IV. China's Optoelectronic Industry Enters a Critical Transformation Window

Optical communication has officially transitioned from a cyclical supporting industry to a high-growth, essential sector for the AI era. According to LightCounting's market forecast, the Ethernet optical module market is expected to grow by 60% in 2026, with total market size surpassing $2 billion.

The formal adoption of the 3.0 concept in optical communications has completed a revaluation of industry value.Optical communications are no longer a supporting industry but the core foundation for building AI, computing power economies, and 6G new infrastructure.。

China currently holds a global leadership position in industrial scale and technological advantages across areas such as silicon photonics chips, high-speed optical modules, fiber-optic cables, and computing power network infrastructure. The advent of the 3.0 era in optical communications will serve as a critical strategic window for China's optoelectronic industry to evolve from scaling up production to strengthening technology, and from exporting products to setting global standards.
