As India races toward becoming a $1 trillion digital economy, the backbone of this transformation—data centers—is under increasing pressure to deliver unprecedented performance while grappling with soaring energy demands and environmental concerns. NTT is betting big on resolving some of these traditional issues with its Innovative Optical and Wireless Network (IOWN), a groundbreaking initiative poised to redefine the future of data centers with its photonics-based All-Photonics Network (APN) technology. Already in its early implementation stages in India, particularly in interconnecting data centers in the Mumbai region, IOWN promises to enhance connectivity, slash energy consumption, and unlock compelling use cases like real-time backups—all while supporting the nation’s ambitious digital and sustainability goals.
For India, this translates into tangible benefits. By minimizing heat generation and reliance on traditional cooling, IOWN could help Indian data centers cut operational costs—critical in a price-sensitive market—while supporting the country’s net-zero ambitions.
At its core, IOWN is a vision for a next-generation communications infrastructure that leverages optical technologies to achieve ultra-high capacity, ultra-low latency, and ultra-low power consumption. Unlike traditional electronic-based networks, which are reaching their physical and energy efficiency limits, IOWN’s APN uses light (photons) to transmit data, offering a transformative leap forward. NTT, a global leader in IT infrastructure and the largest data center provider in India, aims to roll out this technology worldwide by 2030, aligning with the explosive growth of AI-driven data volumes—projected to hit 175 zettabytes by 2025, according to IDC’s Data Age 2025 report. To put this in perspective, that’s enough data to stack DVDs around the Earth 222 times.
In India, where digital adoption is skyrocketing, the implications of IOWN are profound. The country’s data center market, already the largest in Asia-Pacific by capacity, is expected to grow at a CAGR of over 11% through 2030, driven by cloud adoption and 5G rollout. However, this growth comes at a cost: data centers currently consume about 2% of India’s total electricity, a figure set to rise as demand surges. IOWN’s energy-efficient architecture could be a game-changer, addressing both operational scalability and environmental sustainability.
Data centers are notorious for energy consumption, with cooling systems alone accounting for up to 25% of their power usage. In India, where temperatures often soar and renewable energy adoption is still scaling, this poses a significant challenge. IOWN’s APN tackles this head-on by replacing power-intensive electronic components with photonic ones, slashing energy consumption by up to 100 times compared to today’s networks.
Beyond energy efficiency, IOWN unlocks a suite of transformative use cases, with real-time backups standing out as a killer application. Traditional backup systems, hampered by latency and bandwidth constraints, often struggle to keep pace with real-time needs. IOWN’s ultra-low latency—reducing end-to-end delays by over 200 times—enables near-instantaneous data replication across distributed data centers. In a country prone to natural disasters like floods and cyclones, this capability could ensure uninterrupted operations and data integrity, safeguarding economic stability.
Another compelling use case is real-time AI analysis at the edge. India’s smart city initiatives, such as those in Bengaluru and Delhi, depend on processing vast sensor and camera data for traffic management, security, and urban planning. IOWN’s APN, paired with edge computing platforms have shown a 60% latency reduction in aggregating sensor data for AI inference. This could revolutionize applications like predictive maintenance in India’s industrial hubs or telemedicine in rural areas, where low-latency connectivity is often a bottleneck.
Financial services, a cornerstone of India’s economy, also stand to benefit. With IOWN’s demonstrated sub-millisecond latency between data centers, high-frequency trading, remittances, and settlements could become faster and more reliable. For a market like Mumbai, India’s financial capital, this could cement its position as a global fintech hub.
As IOWN matures, its impact on India’s data center landscape could be huge. By 2030, when NTT aims for full commercial realization, India could host a network of hyper-efficient, low-latency data centers powering an AI-driven economy.
