Fiber Optic Sensing Technology for Integrated Utility Tunnels
This study presents a state-of-the-art review of the DFOS applications for monitoring and assessing the deformation behavior of typical tunnel infrastructure, including bored tunnels, conventional tunnels, as well as immersed and cut-and-cover tunnels. This provides a new path for clarifying the key points and difficulties of tunnel engineering monitoring. In addition to its outstanding long-term stability, the technology offers another major advantage: it enables measured values to be transmitted over long distances, with virtually no loss in measurement quality. By providing early warning signs of structural weaknesses or geological shifts, DFOS can play a crucial role in preventing such disasters. According to our latest research, the global Fiber Optic Structural Monitoring for Tunnels market size reached USD 1. 27 billion in 2024, and is anticipated to grow at a robust CAGR of 10.

Long-period fiber grating structure
Structure-Modulated Long-Period Fiber Gratings (SM-LPFGs) represent an advancement in fiber optic sensor technology, moving beyond traditional photosensitivity-based fabrication to achieve enhanced performance through the direct physical modification of the geometry of the fiber. This review. A long-period fiber grating couples light from a guided mode into forward propagating cladding modes where it is lost due to absorption and scattering. As a band rejection filter, all light in a spectral slice is discarded without affecting the amplitude and phase of neighbouring wavelengths, with the additional advantage of low insertion losses. In this paper, we rigorously deduce the coupled-mode equations of a long-period fiber grating and fiber Bragg grating in their cascaded structure (CLBG), based on coupled-mode theory. Next, through the difference iterative method, the total transfer matrix of CLBG is obtained.
