섬유 브래그 그레이팅 센서 : 시장 점유율 분석, 업계 동향 및 통계, 성장 예측(2026-2031년)

The Fiber Bragg Grating Sensor market is expected to grow from USD 0.83 billion in 2025 to USD 0.9 billion in 2026 and is forecast to reach USD 1.33 billion by 2031 at 8.21% CAGR over 2026-2031.

The surging adoption of structural health monitoring, hydrogen pipelines, smart mining, and 5G backhaul infrastructure underpins this steady trajectory. Competitive differentiation centers on wavelength-dense sensor networks, multi-parameter measurement capabilities, and artificial intelligence-based signal processing. Rising infrastructure investments, safety-centric regulations, and the operational limits of traditional electrical gauges jointly favor optical sensing. Nevertheless, cross-sensitivity between temperature and strain, as well as higher upfront installation costs, continue to moderate near-term adoption in price-sensitive deployments.

Global Fiber Bragg Grating Sensor Market Trends and Insights

Growing Demand for Real-Time Structural Health Monitoring

Aging bridges, tunnels, and high-rise buildings are now monitored continuously with dense arrays of fiber Bragg gratings that reveal fatigue cracks and patterns of load redistribution before structural failure. The 2024 Francis Scott Key Bridge collapse accelerated federal mandates for continuous monitoring on high-traffic corridors in the United States. Distributed sensing along entire girders creates a complete strain profile, replacing scattered electrical gauges that overlook early-stage anomalies. Similar regulations in Europe tie public-funded infrastructure upgrades to the adoption of optical sensing, positioning the Fiber Bragg Grating Sensor market for long-term demand in civil assets.

Adoption in Hydrogen Pipeline Networks

Europe's Hydrogen Backbone initiative requires leak detection systems immune to hydrogen embrittlement, elevating fiber Bragg gratings as a safety standard. Dual-mode acoustic and strain detection enables operators to spot micro-leaks and mechanical deformation simultaneously, a capability that electrical systems cannot deliver in the corrosive hydrogen environment. Germany's H2-Netz specifications for new transmission lines create a replicable template that North American and Asia-Pacific projects are beginning to follow, widening the Fiber Bragg Grating Sensor market footprint in energy transport infrastructure.

Cross-Sensitivity to Temperature and Strain

Separating mechanical strain from thermal effects still necessitates costly dual-grating configurations or computational compensation that introduce 5-10% measurement uncertainty in aerospace and energy applications. Customers seeking +-1% accuracy often resort to redundant sensor schemes, which raises project budgets and hinders adoption in environments with wide thermal swings. This technical hurdle temporarily tempers the expansion of the Fiber Bragg Grating Sensor market until advanced compensation designs become price-competitive.

Other drivers and restraints analyzed in the detailed report include:

1. Rising Investments in Smart Mining Operations
2. Expansion of 5G Fiber Backhaul Infrastructure
3. High Upfront Installation Cost versus Electrical Gauges

Segment Analysis

Strain sensors contributed USD 0.31 billion to the Fiber Bragg Grating Sensor market in 2025, retaining a 37.78% revenue share, which underscores their ubiquity across bridges, aircraft wings, and concrete structures. Acoustic variants, while smaller in absolute terms, show a 9.12% CAGR as distributed acoustic sensing gains traction in perimeter security and leak detection. Strain devices will continue to anchor flagship infrastructure projects, but acoustic systems provide a high-growth complement.

Multi-parameter hybrids that co-locate strain and temperature gratings on a single fiber are shrinking compensation errors and lowering channel counts. Oilfield service providers are increasingly favoring combined sensors to reduce wellbore completion complexity, thereby broadening the reach of the Fiber Bragg Grating Sensor market across downhole conditions where electronic gauges fail.

The dominant C-Band segment generated nearly USD 0.37 billion in 2025, driven by telecom-grade component availability and proven interrogation hardware. Network-scale projects exhaust available C-Band channels, driving migration to the L-Band, which is posting the fastest 9.32% CAGR. The Fiber Bragg Grating Sensor market size for L-Band devices is forecast to expand significantly as mega-projects demand hundreds of sensing points on a single fiber.

Advanced interrogators now sweep across C- and L-Bands simultaneously, enabling mixed architectures that balance component cost with channel density. Research consortia are testing broader O-Band arrays for niche biomedical and underwater applications, although commercialization remains modest compared to mainstream wavelengths.

The Fiber Bragg Grating Sensor Market Report is Segmented by Type (Temperature Sensor, Strain Sensor, and More), Grating Wavelength Range (C-Band, L-Band, and More), End-User Industry (Telecommunication, Aerospace and Defense, and More), Application (Structural Health Monitoring, Temperature Monitoring, Vibration and Acoustic Monitoring, and More), and Geography. The Market Forecasts are Provided in Terms of Value (USD).

Geography Analysis

North American revenue leadership stems from mandated structural monitoring after catastrophic bridge failures. Federal grants subsidize installation on aging steel arches, and the U.S. Navy's submarine hull integrity program extends military demand. Canada's extreme temperature swings make optical sensors a logical choice for remote transmission lines prone to ice loading. Mexico adopts fiber arrays in automotive factories to reduce unplanned downtime, adding a nascent industrial layer to the regional Fiber Bragg Grating Sensor market.

Asia-Pacific's dynamism is evident in China's multi-province high-speed rail rollout, with each viaduct equipped with thousands of gratings to detect rotational slip and joint displacement. Japan's stringent seismic codes drive real-time monitoring on new Shinkansen stations, while Korea integrates sensors into 5G trunk lines to localize fiber cuts within meters. India's smart-city program funds pilot traffic-monitoring grids using distributed acoustic sensing on roadway shoulders, thereby expanding the addressable demand.

Europe benefits from standardized regulations that align hydrogen, wind, and rail projects under frameworks like IEC 61757. Germany's H2-Ready pipeline criteria specify acoustic leak detection by default, and the United Kingdom's Crown Estate requires optical monitoring on fixed and floating wind assets. Southern Europe channels recovery funds into high-speed rail that crosses seismic zones, mandating optical arrays for tunnel liner strain measurement, buttressing the regional Fiber Bragg Grating Sensor market outlook.
