Masahisa Kawashima, IOWN Technology Director at NTT, discusses how IOWN (Innovative Optical and Wireless Network) technology will transform financial services. IOWN's photonic infrastructure enables high-speed, low-latency, and highly reliable data transfer, essential for financial institutions requiring seamless AI and data-driven operations. It allows for efficient, scalable, and sustainable data center operations by reducing power consumption through decentralized setups in suburban areas. IOWN’s infrastructure will also enhance security, operational resilience, and disaster recovery. The technology aims to provide banks with high-bandwidth, low-latency connectivity for AI computing, improving business continuity and data management. While large-scale deployment may take a few years, IOWN is positioning itself as a key enabler for the next generation of digital financial services
