Specialty cable knowledge brief Published 08 May 2025

Prepared for preliminary research by the ZITHA SPECIALTY knowledge desk. Confirm fire performance, mechanical protection, loss budgets and installation requirements against current standards and product documentation.

Belgium has been a key hub for fiber optic sensing innovation, with Sentea and research groups at Ghent University and B-PHOT leading the development of advanced FBG and microstructured optical fiber sensors.Key Players and Research

Sentea, founded in 2018 as a spin-off from Ghent University's Photonics Research Group (PRG) and imec, commercializes over a decade of research in silicon photonics-based fiber optic sensing . Their technology focuses on fiber Bragg grating (FBG) sensors and cost-effective interrogators, enabling precise monitoring of strain, temperature, vibration, and other parameters across civil, industrial, and renewable energy applications . Sentea's sensors are particularly valued for their robustness, small size, and immunity to electromagnetic interference, making them suitable for harsh environments . At B-PHOT (Vrije Universiteit Brussel), research emphasizes microstructured optical fibers (MOFs) and FBG-based sensors with high sensitivity to pressure, transverse force, and shear strain while minimizing temperature cross-sensitivity . These sensors have been integrated into composite materials for structural health monitoring, enabling simultaneous measurement of multiple strain components and detection of residual stresses in industrial applications .

Technology and Applications

Belgian fiber optic sensing leverages FBG and MOF technologies to convert optical signals into measurable physical parameters. FBG sensors use periodic refractive index modulations in the fiber core to detect sub-micron deformations or temperature changes with high precision . MOFs enhance sensitivity to mechanical forces and allow integration into complex materials for industrial and civil engineering monitoring . Applications include:

  • Structural Health Monitoring (SHM): Bridges, buildings, wind turbines, nuclear plants, and tunnels benefit from continuous monitoring to detect early signs of damage, prevent catastrophic failures, and extend asset lifetimes .
  • Industrial Process Control: Motors, bearings, drive trains, and chemical processes are monitored for efficiency and predictive maintenance .
  • Smart Infrastructure: Fiber optic sensors integrated with existing fiber networks enable smart city and smart grid monitoring, supporting IoT and edge computing applications .
  • Medical and Aerospace: High-precision FBG sensors are used in surgical instruments and aerospace structural monitoring, including UAVs and spacecraft components .
Advantages

Belgian fiber optic sensing technologies offer:

  • High spatial resolution and distributed sensing over kilometers of fiber
  • Passive operation with low attenuation and immunity to electromagnetic interference
  • Compact, lightweight, and robust sensors suitable for harsh environments
  • Cost-effective interrogators through silicon photonics integration, enabling broader adoption
Conclusion

Belgium's contributions to fiber optic sensing, particularly through Sentea, Ghent University, and B-PHOT, have established the country as a leader in advanced FBG and MOF sensor technologies. These innovations support structural health monitoring, industrial process optimization, and smart infrastructure, combining high precision, robustness, and cost-effectiveness to meet modern engineering and industrial challenges .
