According to data from the European Commission's 2022 Digital Economy and Society Index, Spain ranks in the top 10 of EU states in all four areas being assessed – human capital, connectivity, integration of digital technology and digital public services. As per Market Research Future analysis, the Spain Fiber Optic Sensor Market size was estimated at 57. 53 USD Million by 2035, exhibiting a compound annual growth rate (CAGR) of 7. 6% during. Fiber optic sensing solutions for cable condition monitoring and optimization of performance: Real Time Thermal Raiting (RTTR) and Depth of Burial (DoB). In a bid to maintain their world-leading position, operators in the sector expect to be able to offer full fibre optic coverage by the end of 2024. Aragon Photonics works together with leading research centers and universities in its sector, patenting, designing, manufacturing and maintaining. Because of that, we started working on a new technique, the Electrostatic Self-Assembly Monolayer (ESA) process to build up coatings on the ends of optical fibers with the goal of fabricating sensors for measuring different parameters such as humidity or harmful gases, among others. The sensor contains a light source (transmitter), typically an LED, and a photodiode (receiver).
