tending cable lengths beyond the limitations of copper cabling. This means that active optical cable assemblies will play a pivotal role in enabling applications such as real-time traffic monitoring. Moreover, fiber optic cables offer greater reliability compared to traditional cables, as they are resistant to electromagnetic interference, ensuring stable and secure connections. This depend- ability is essential for the effective operation of critical smart city infrastructures. Power-over-Fiber (PoF) is a technology that enables power delivery through optical fibers to remote nodes, thereby reducing electromagnetic interference and enhancing energy efficiency. The technology can be integrated into existing telecommunications infrastruc- ture, facilitating the development of smart infrastructure through dynamic reconfiguration and improved user service throughput 3 . Additionally, PoF supports cen- tralized power monitoring and management, which are essential for maintaining service quality and operational efficiency in modern smart networks. Examples of PoF use cases within smart infrastructure include powering streetlights with motion sensors, cameras, and environmental monitors to achieve en- ergy-efficient, responsive lighting and enhanced safety. PoF can also support traffic cameras, vehicle detection, and digital signage on motorways and in urban areas for reliable, interference-free operation and streamlined transport. Supplying PoF for sensors, access systems, and energy monitors in smart buildings and substations will enable centralized management, reduce cabling, and boost operational efficiency. While smart infrastructure presents tremendous oppor- tunities to create more efficient, safe, and sustainable urban environments, significant challenges must be addressed to realize its full potential. Cybersecurity remains a critical concern, as sensor networks and con- nected devices are vulnerable to attacks that can disrupt services, compromise privacy, and spread misinforma- tion. The high costs and complexities of installing and upgrading IoT and IT systems require careful planning, ensuring infrastructure is scalable, flexible, and capa - ble of handling vast amounts of data. Environmental factors such as exposure to dust, water, UV damage, vibration, and temperature fluctuations demand robust, sealed, and proven hardware solutions. Overcoming these challenges with innovative technologies and strategic implementation will be essential to unlocking the transformative benefits of smart infrastructure for future cities.
