Optical Switches Market: AI Data-Center Power Pressure, Fiber Expansion, and Optical-Network Modernization Shift Revenue Toward OCS and WSS Platforms

The Global Optical Switches Market is projected to grow at a CAGR of 10.5%, increasing from USD 3.76 billion in 2025 to USD 7.56 billion by 2032, according to Strategic Market Research.

 

Optical switch revenue is moving beyond telecom hardware as AI data centers, cloud interconnects, undersea networks, and fiber-monitoring systems place higher value on power efficiency, network uptime, and flexible capacity expansion. Hyperscale data centers provide the strongest commercial proof. Google reported that its Jupiter data-center network supports more than 6 Pb/sec of bandwidth and delivers 40% lower power use, 30% lower cost, and 50x less downtime than the best known alternatives. Those operating gains link optical switching directly to data-center cost control, power planning, and resilience.

 

AI Power Economics Are Pulling Optical Switching Into Data-Center Capex Plans

AI infrastructure is creating the clearest growth path for optical switches because network expansion is now tied to electricity availability and capital efficiency. The International Energy Agency estimated global data-center electricity consumption at around 415 TWh in 2024 and projected it to reach about 945 TWh by 2030. It also reported that accelerated servers, mainly driven by AI, are projected to grow electricity use by 30% annually in its base case. Large data-center operators are prioritizing network architectures that can expand capacity without adding the same level of electrical switching, conversion losses, and power overhead.

Commercial adoption is broadening across hyperscale operators, optical-switch suppliers, and network ecosystem partners. Google has already used optical circuit switching in production-scale data-center networks. Huber+Suhner received significant POLATIS OCS orders from a global hyperscale data-center owner/operator in July 2025. Coherent introduced a 300x300-port optical circuit switch for AI data centers in 2024, with volume shipments expected to begin in 2025. Marvell and Lumentum announced a 2026 live demonstration of Marvell optical connectivity interoperating with Lumentum’s R300 OCS platform. These developments reduce the risk that OCS remains dependent on one hyperscaler’s internal design and show wider supplier participation around AI network scaling.

 

Multi-Year Hyperscale Orders Are Moving OCS From Pilot Demand to Planned Procurement

Huber+Suhner’s OCS activity gives the market one of its strongest supplier-side indicators. The company opened a dedicated POLATIS optical circuit switch production site in Pisary, Poland in June 2025, with production capacity planned to increase at least fivefold over two years. One month later, it announced major hyperscale OCS orders under a multi-year cooperation agreement expected to generate substantial sales over the next three years. Capacity expansion followed by a multi-year order signal indicates that AI data-center OCS demand is entering planned procurement cycles rather than isolated pilot projects.

Lumentum adds another supplier-level signal from the broader optical-networking value chain. Its Cloud & Networking revenue reached USD 1.41 billion in FY2025, up 30.0% from FY2024, while Q4 FY2025 Cloud & Networking revenue rose 66.5% year over year. While this revenue category extends beyond optical switches, the growth rate indicates that cloud and AI data-center customers are increasing procurement across optical networking platforms and components. Optical-switch suppliers benefit from this budget shift as OCS platforms, optical components, DSPs, WSS products, and data-center interconnect technologies compete for a larger share of AI infrastructure spending.

 

Open OCS Standards Are Expanding the Supplier Base Beyond Custom Hyperscale Networks

Adoption beyond custom hyperscale networks depends on interoperability, software control, and vendor choice. The Open Compute Project announced a new Optical Circuit Switching subproject in July 2025 to support open OCS technologies for AI and data-center networking. Initial participants include Coherent, Google, Lumotive, Microsoft, nEye, NVIDIA, Oriole Networks, POLATIS, iPronics, and Lumentum. A multi-company standards forum lowers the risk that OCS remains limited to custom networks designed by a few hyperscalers.

Open architectures improve supplier access to cloud service providers, colocation operators, and AI infrastructure companies that do not design every network layer internally. Marvell and Lumentum’s 2026 interoperability demonstration follows the same direction, positioning OCS platforms alongside optical DSPs, telemetry, and data-center connectivity systems. Buyers can evaluate optical switching as part of a wider network ecosystem rather than treating it as a standalone hardware risk.

 

Undersea and Carrier Networks Keep WSS Revenue Tied to Reliability and Field Proof

Telecom and undersea networks remain a separate revenue stream from AI data-center OCS. Coherent reported that II-VI had shipped more than 1,000 LightFlow Flexband wavelength selective switch modules for undersea optical networks since receiving its first commercial orders in 2019. Undersea deployments require long qualification cycles, field reliability, and supplier credibility. Those requirements protect WSS pricing better than commodity optical-switch procurement because replacement risk, route continuity, and carrier acceptance carry more weight than upfront unit cost.

Lumentum’s Cloud & Networking revenue reached USD 1.41 billion in FY2025, up 30.0% from FY2024, while Q4 FY2025 segment revenue increased 66.5% year over year. The segment includes products beyond optical switches, but the growth reflects stronger spending by cloud operators and telecom customers on high-capacity optical infrastructure.

 

Fiber Buildouts Are Adding Monitoring, Testing, and Transport-Switching Revenue

Fiber-network expansion supports the lower and mid-value layers of the optical switches market. The Fiber Broadband Association reported that FTTH deployment reached 76.5 million unique U.S. homes passed in 2024, up 13% from the previous year. In Europe, the FTTH Council Europe reported 269 million FTTH/B homes passed across EU39 in September 2024, with 143 million subscribers. Larger fiber footprints increase the installed base that requires monitoring, test access, route protection, transport upgrades, and maintenance-linked switching equipment.

The UK shows how fiber maturity can translate into network operations demand. Ofcom reported that full fiber was available to 24.9 million UK residential premises, or 82% of homes, as of January 2026. Full-fiber connections across residential and commercial premises increased by 1.8 million in six months to reach 12.4 million. Higher fiber penetration shifts operator spending from new passings alone toward service assurance, monitoring, traffic management, and network resilience. Optical switches used in test networks, fiber-monitoring systems, and carrier transport upgrades gain from that operational spending shift.

 

Internet Exchange Traffic Is Raising the Case for Backbone Optical Upgrades

High-volume internet exchanges are increasing demand for optical transport switching. DE-CIX reported that its global platforms exchanged 79 EB of data in 2025, up 16% from 2024 and 147% higher than 2020. Frankfurt alone reached 48 EB in 2025, up 6% from 2024 and 65% higher than in 2021. Dense traffic flows increase the need for flexible optical transport, route diversity, and high-capacity backbone upgrades. Optical switches gain value where operators need to move traffic across major interconnection hubs without adding excessive electrical conversion cost.

Internet exchange operators, carriers, and hyperscalers create different revenue timing for optical-switch suppliers. Exchange and carrier customers typically invest through planned network upgrades, while hyperscalers invest through cluster expansion and internal architecture cycles. AI data-center OCS can generate larger order events when a platform is selected for a deployment program. Carrier WSS and optical transport switching revenue is steadier but more exposed to telecom capex delays, inventory digestion, and project timing. Suppliers serving both areas can reduce cyclicality, provided they meet different qualification and reliability requirements.

 

U.S. AI Power Load Favors Premium OCS, While Europe Builds Demand Through Fiber and Exchange Hubs

The U.S. is the strongest region for premium OCS demand because it concentrates hyperscale cloud, AI infrastructure, and data-center power pressure. IEA reported that the United States accounted for 45% of global data-center electricity consumption in 2024, ahead of China at 25% and Europe at 15%. It also projected that U.S. data-center electricity consumption could increase by about 240 TWh by 2030, up 130% from the 2024 level. Power growth at this scale strengthens demand for optical-switch architectures that reduce energy use and improve network upgrade economics.

Europe’s opportunity is more balanced across fiber networks, internet exchanges, and telecom modernization. EU39 had 269 million FTTH/B homes passed and 143 million subscribers in September 2024, while DE-CIX Frankfurt remained a major traffic hub with 48 EB exchanged in 2025. The region is attractive for WSS, ROADM-related switching, fiber monitoring, and backbone upgrades. European demand is less dependent on one buyer group than the U.S. AI data-center market, giving suppliers a wider but more fragmented customer base.

 

OCS Captures Premium Growth While WSS and Monitoring Switches Protect Specialist Revenue

Optical circuit switches are the most strategically important growth segment because AI data centers are under direct pressure to reduce power and capex per unit of network capacity. Google’s production evidence, Huber+Suhner’s hyperscale orders, Coherent’s OCS launch, Marvell-Lumentum interoperability work, and the OCP OCS subproject create a multi-source demand case. The segment is likely to remain concentrated among suppliers that can pass long qualification cycles and support large-port-count, software-controlled deployment models.

Wavelength selective switches remain the core telecom optical-switching segment. Coherent’s undersea WSS shipment milestone and Lumentum’s WSS recognition show that the segment is still supported by carrier-grade reliability and network modernization. Growth here is less explosive than AI data-center OCS, but buyer stickiness can be stronger because field-proven performance matters in long-haul, subsea, and ROADM environments.

Fiber-monitoring and test-network optical switches form a more procurement-driven segment. The supplied research brief cites an Indian railway fiber-monitoring tender with five optical-switch-based RTUs, INR 9.10 million in equipment value, and a 48-month operations and maintenance component. This segment is more price-sensitive than hyperscale OCS or undersea WSS, but service contracts can improve lifetime revenue. Suppliers that combine competitive hardware pricing with monitoring, maintenance, and public-sector support capabilities can win recurring value even where tender pricing limits margins.

 

Deployment Proof, Manufacturing Scale, and Ecosystem Access Decide Supplier Positioning

Optical-switch supplier selection is increasingly driven by demonstrated deployment performance and commercial validation. Hyperscale buyers require evidence that OCS can lower power consumption, reduce network cost, and improve availability at scale. Telecom operators prioritize field reliability, interoperability, and carrier-grade qualification. Public infrastructure buyers focus on transparent pricing, lifecycle support, and service continuity. Vendor claims carry limited weight without deployment references because optical-switching decisions influence network uptime, capital allocation, upgrade timing, and long-term operating expenditure.

Google, Huber+Suhner/POLATIS, Coherent, Lumentum, Marvell, and OCP represent different parts of the competitive map. Google validates the production economics. Huber+Suhner shows commercial hyperscale ordering and capacity expansion. Coherent brings both WSS deployment history and a data-center OCS product. Lumentum connects cloud networking growth with WSS and OCS ecosystem participation. Marvell strengthens the OCS architecture case through optical connectivity interoperability. OCP gives buyers a path toward standardization. Suppliers that combine deployment proof, manufacturing scale, ecosystem alignment, and service credibility are better positioned to capture higher-value optical-switch revenue.

AI data-center power pressure, fiber expansion, and interconnection traffic growth are shifting optical-switch revenue toward suppliers that can prove network-level cost reduction, uptime gains, and scalable production. OCS will capture the highest-growth AI infrastructure opportunities, WSS will retain value in carrier and undersea networks, and monitoring switches will add service-linked revenue across expanding fiber footprints. The market’s strongest suppliers will be those that convert technical credibility into repeat deployment programs, open ecosystem participation, and long-term infrastructure contracts.
