NTT is advancing its IOWN (Innovative Optical and Wireless Network) initiative toward the commercialization of version 2.0, focusing on the expansion of its computing business and optical-electronic convergence technology.
Context
Japanese telecommunications giant NTT is accelerating its transition toward the commercialization of IOWN 2.0 by 2025. While the initial phase focused on the All-Photonics Network infrastructure, this next iteration integrates photonics-electronics convergence directly into chip-level hardware. This shift signals NTT’s aggressive expansion from a traditional carrier into a high-performance computing provider, leveraging proprietary optical technologies to address the massive power and scaling bottlenecks currently facing the generative AI sector.
The move is a significant milestone for the semiconductor supply chain, aiming to deliver a 100-fold increase in power efficiency and a 125-fold boost in transmission capacity. By implementing optical chiplets at the board level, NTT targets a reduction in end-to-end latency by a factor of 200. These advancements position the company to capture market share in the AI server and data center markets, offering a sustainable alternative to current silicon-based architectures that are struggling with rising energy demands.
