In the field of optical communications, the technology of fiber optic intelligent sensing is developing rapidly and becoming a highly transformative frontier. With the vigorous rise of 5G, the Internet of Things (IoT), and industrial internet, there is a surge in demand across various industries for precise, reliable, and real-time sensing. Fiber optic intelligent sensing stands out with its unique advantages such as immunity to electromagnetic interference, high sensitivity, and long-distance distributed monitoring, making significant contributions in sectors like energy, transportation, construction, and healthcare. Moreover, with digital transformation, breakthroughs in integrated communication and sensing technology within optical networks have opened up new dimensions for fiber optic sensing. By reusing existing fiber optic infrastructure, communication and sensing signals can be transmitted over the same fiber, achieving dual functions of communication services and environmental monitoring through a single network. Integrated communication and sensing technology in optical networks has become a crucial support for high-precision sensing scenarios in smart cities and industrial internet, promoting deep synergy between fiber optic communication networks and intelligent sensing systems.

However, the integration of current technologies still faces multiple challenges, such as signal crosstalk, attenuation of sensing accuracy across relays, and constraints on large-scale deployment due to insufficient domestication rates of components. Further breakthroughs are needed in areas like multi-physical field coupling interference decoupling, miniaturized packaging processes, and dynamic response speed. Against this backdrop, the "Fiber Optic Intelligent Sensing Technology Session" will bring together industry experts to focus on innovations in integrated communication and sensing architectures, cutting-edge fiber optic sensing technologies, and industry application practices. The aim is to facilitate the deep integration of communication and sensing functionalities, jointly promoting the intelligent upgrade of networks and the development of the fiber optic sensing industry.
