Addressing the current monitoring challenges in urban confined spaces, this study aims to explore an integrated monitoring and communication system based on fiber-wireless convergence. By integrating micro-nano units into a unified optical cable for communication and power supply, and applying multi-parameter monitoring, a novel solution for simultaneous energy and signal transmission is proposed. The research consists of three main parts: long-distance fiber-optic energy and signal transmission, photoelectric conversion, and the integration of magnetic resonance wireless power transfer. Additionally, it includes system integration and application exploration of these key technologies. Through in-depth research on high-efficiency photoelectric conversion technology, short-distance wireless power transfer based on magnetic resonance, and the design and development of a unified optical cable for communication and power supply, this study constructs a comprehensive theoretical framework and provides experimental validation. This research offers new directions and practical cases for integrating of fiber-optic and wireless technologies. The outcomes expand the application fields of fiber-optic communication and wireless sensing technologies and provide innovative technical support and solutions for critical areas such as power grids and urban infrastructure monitoring.
