Abstract
To explore the critical role and technological trends of optical communication networks in smart city development,this study systematically analyzes the application scenarios and performance of three key technologies:free-space optical communica-tion(FSO),integrated sensing and communication(ISAC)optical networks,and visible light communication(VLC).Furthermore,based on the latest advancements in novel optical fibers,optoelectronic device manufacturing,and quantum communication tech-nologies,future development directions are proposed.The analysis reveals that FSO offers high-speed transmission advantages for cross-domain connectivity and emergency communications but suffers from weather-dependent instability.ISAC-enabled optical networks facilitate real-time monitoring in scenarios such as traffic and seismic activity through fiber-optic sensing,yet exhibit high false alarm rates in complex environments.VLC achieves centimeter-level precision and interference-free transmission in in-door positioning and medical applications but faces challenges in hardware cost.Looking ahead,hybrid hollow-core and mul-ti-core fiber architectures,co-packaged optics(CPO),and quantum key distribution(QKD)are expected to drive smart city advanc ements in network infrastructure,energy-efficient device interconnection,and security enhancement,respectively.关键词
