An Optical Circuit Switch (OCS) is an advanced network device based on optical signal processing technology. By utilizing optical channels for data exchange, it enables high-speed, low-latency, and high-bandwidth network connectivity. Unlike traditional switching devices that rely on electronic signal processing, optical circuit switches eliminate the need for optical-to-electrical conversion during signal transmission and switching, effectively reducing energy consumption, minimizing latency, and significantly improving data processing efficiency. These devices offer advantages such as rapid port switching speed, high concurrency, no packet loss, and low energy consumption, making them ideal for scenarios requiring extremely high network performance, such as large-scale data centers, cloud computing platforms, high-performance computing systems, and artificial intelligence training environments. Optical circuit switches can perform path switching at microsecond-level speeds, enabling flexible resource allocation and dynamic network reconstruction to meet the demands of future high-speed interconnectivity. With the continuous growth of data traffic and the increasing demand for computational power, optical circuit switches are becoming a crucial component of next-generation high-performance network architectures, providing essential support for building efficient, green, and intelligent communication infrastructures.

Optical Circuit Switch (OCS) Development Status

According to DIResearch statistics, In Q1 2026, China's Optical Circuit Switch (OCS) industry chain maintained a strong growth trend. The average net profit of listed companies in the sector increased by 128% year-on-year, far exceeding the industry's average growth rate of 8.7%. This growth further highlighted the sector's differentiation and structural prosperity. The majority of the growth occurred in high-value-added segments. System integrators, benefiting from enhanced integration capabilities and large-scale delivery volumes, saw a 210% increase in growth. Optical module companies experienced a 150% increase, driven by the demand for high-speed optical interconnections. The upstream optical devices and key materials sectors grew steadily by 85%. The entire industry chain is now transitioning from technology introduction to large-scale commercial implementation, entering a crucial acceleration phase.

Industry leaders have entered a "dual-growth cycle" driven by both orders and capacity expansion. Core companies, such as optical module and system integration manufacturers, saw a surge in orders from overseas cloud vendors and AI data center clients in Q1 2026. Some companies are already expanding production lines and upgrading automation to meet the demand for faster delivery cycles and improved yields for high-speed optical switching equipment. Additionally, several companies are vertically integrating into core technology segments like OCS-specific chips, MEMS optical switches, and high-speed optical engines to increase their value share and bargaining power within the all-optical network.

The OCS industry's growth is being driven by the global restructuring of computational infrastructure. Major chip companies like NVIDIA and AMD have launched next-generation AI chips supporting OCS-based all-optical interconnect architectures. As a result, large-scale data centers are accelerating their shift from electrical switching to all-optical switching. This change is gradually extending OCS from internal data center connections to multi-level scenarios, including cloud computing centers, edge computing nodes, and AI training clusters. Leading cloud providers have already started incorporating OCS into the design standards for next-generation AI infrastructure, signaling the industry's shift toward "optical-electronic fusion architecture restructuring."

The market outlook and order data further validate this growth. A recent Morgan Stanley report revealed that the global OCS market will grow rapidly from $780 million in 2025, reaching $2.35 billion in 2026—a nearly 200% year-on-year increase. By 2030, the market is expected to reach $6 billion, solidifying it as a long-term high-growth sector. In terms of actual deployment, Google, as one of the OCS commercialization leaders, issued orders for over 47,000 OCS devices to Chinese supply chain companies in Q1 2026, totaling $1.15 billion. This accounts for approximately 65% of its annual procurement plan. More than 90% of these orders were handled by A-share listed companies and their core suppliers, directly boosting the order volumes and capacity utilization of optical module, system integration, and key component manufacturers, driving the strong performance of related companies in China.

Global Optical Circuit Switch (OCS) Technology Pathways

With the rapid growth in AI computational demands and the continuous evolution of data center network architectures, Optical Circuit Switch (OCS) technology is emerging as a key solution to overcome the bandwidth and power consumption limitations of traditional electrical switching. OCS is gradually transitioning from the laboratory to large-scale deployment. Currently, four major technological pathways dominate OCS development: MEMS, Liquid Crystal, Piezoelectric Ceramic, and Silicon Photonic Waveguides. Among them, MEMS holds a leading position due to its mature engineering capabilities and scalability, making it the core solution for large-scale port switching, such as 300×300 and beyond. Liquid crystal technology, represented by companies like Coherent, is gaining traction as a potential alternative, with its high reliability and low power consumption. Piezoelectric and silicon photonic solutions show promise in the areas of low loss and high integration. Companies such as Google, Coherent, Calient, DiCon Fiberoptics, Huawei, and iPronics are advancing along these different technological pathways, pushing OCS from technology validation to real-world applications in AI data center environments. The global industry is emerging into a "MEMS-dominant, multi-path competition" phase.

MEMS Solution (Current Mainstream and Scalable Core)

MEMS optical switches use micro-mirror arrays to alter the optical path in space, connecting input and output ports. This is the most mature and widely adopted OCS technology. Typical MEMS configurations include 1×N, 2D N×N, and 3D N×N, with the 3D MEMS design becoming the mainstream architecture as it requires only 2N mirrors for large-scale connectivity, supporting port scales of 300×300 and beyond. Google’s Apollo OCS, for instance, uses 3D MEMS mirrors for large-scale optical path reconfiguration in data centers, which has already been deployed in AI clusters, significantly reducing power consumption and improving network flexibility. Calient and DiCon Fiberoptics are also pushing the commercialization of MEMS solutions, offering mature products for 300×300 port scales and above. Huawei has launched a 256×256 OCS system based on MEMS, gradually penetrating data center applications. Overall, MEMS still holds a dominant advantage in terms of scalability and engineering maturity. However, the complexity of mechanical control, yield issues, and long-term reliability remain significant bottlenecks for further expansion.

Liquid Crystal Solution (High Reliability Alternative Pathway)

Liquid crystal optical switches modulate the arrangement of liquid crystal molecules using an electric field to alter the polarization state of light, in combination with polarization beam splitters to enable optical path switching. The main advantage of this solution lies in the absence of mechanical moving parts, offering significant benefits in terms of reliability, stability, and power consumption. Coherent’s Digital Liquid Crystal (DLC) technology, for example, has achieved large-scale commercialization in Wavelength Selective Switches (WSS) and further expanded into OCS, supporting port scales of 300×300 and even higher. Compared to MEMS, liquid crystal technology offers better long-term operational stability and fault rate control. However, its switching time typically falls within the millisecond range (approximately 50–100 ms), making it more suitable for AI data center environments where real-time demands are less critical, but reliability is paramount.

Piezoelectric Ceramic Solution (Low Loss and High Precision)

Piezoelectric ceramic optical switches leverage electromechanical coupling effects to drive changes in the position and angle of collimators, enabling direct alignment of light beams (DLBS technology). This solution has inherent advantages in terms of insertion loss and return loss, as the optical signal does not pass through complex reflection paths, and the optical path is shorter. Additionally, piezoelectric solutions offer superior long-term stability compared to MEMS. Polatis, a subsidiary of HUBER+SUHNER, represents this solution, with its DLBS technology being competitive in medium-scale optical switching. However, as port scales increase, the demands for displacement accuracy, structural space, and control complexity grow, limiting the applicability of this solution in large-scale OCS systems (300×300 and above). It is currently more suited for high-performance, medium-scale scenarios.

Silicon Photonic Waveguide Solution (High Integration and Future Path)

Silicon photonic waveguide solutions construct optical path matrices on a chip, enabling on-chip routing and switching of optical signals. This technology offers extremely high integration and potential cost advantages, with switching speeds reaching the microsecond or even nanosecond range. It is particularly suited for future integration with Co-Packaged Optics (CPO), enabling chip-level optical interconnects. iPronics is a representative company that has developed a 32-port silicon photonic OCS product, using a programmable photonic architecture for flexible optical path configuration, while also participating in the development of OCP OCS standards. However, the silicon photonic solution still faces issues such as insertion loss, crosstalk, and cumulative losses associated with large-scale integration. To compensate for these losses, Semiconductor Optical Amplifiers (SOA) are often required, which adds complexity to the system. As such, silicon photonics has not yet entered the mainstream competition for 300×300 port scales.

According to DIResearch, the global Optical Circuit Switch (OCS) market is expected to reach $1,113 million in 2026, with projections to grow to $3,080 million by 2033, representing a compound annual growth rate (CAGR) of 15.65% from 2026 to 2033. The OCS industry is accelerating its development driven by the demand for AI computational power. OCS technology has already begun to be adopted in large-scale data centers, with North America accounting for the largest share of global demand, approximately 35%–40%. Cloud vendors in the U.S., such as Google, are leading the way in deploying OCS in AI cluster networks, using MEMS-based optical switching architectures to significantly enhance network capacity and reduce energy consumption (with some systems achieving up to a 40% reduction in power usage). This region has become the core driver of both technological development and commercialization.

In contrast, the Asia-Pacific region, especially China, plays a key role in manufacturing and system integration within the OCS industry. Leveraging the expertise of companies like Huawei in optical communications and data center networks, China continues to make breakthroughs in the engineering and large-scale application of OCS. Additionally, the region possesses strong manufacturing capabilities in MEMS devices, optical modules, and system integration. Meanwhile, Europe and Japan primarily focus on upstream components such as high-end optical devices, lasers, and precision materials, providing essential support for the global OCS industry. Overall, the global OCS industry is forming a division of labor with "North America leading demand and architecture, Asia-Pacific driving manufacturing and system implementation, and Europe and Japan supplying critical components."
