The NTT (Nippon Telegraph and Telephone Corporation) logo is prominently displayed on a transparent MicroLED screen at the entrance of the company's pavilion during the Mobile World Congress in Barcelona, Spain, on March 5, 2026. NTT's exhibit for 2026, themed ''IOWN for AI and Sustainability,'' highlights the global commercial readiness of the All-Photonics Network (APN). Live demonstrations feature the deployment of IOWN APN connections using NTT's optical line terminals powered by the in-house designed APN single-chip LSI, utilizing silicon photonics to achieve deterministic, ultra-low latency data transmission below 0.1ms. The stand also showcases the deployment of NTT's specialized large language model, ''tsuzumi,'' optimized for energy efficiency using IOWN's disaggregated computing architecture. It runs on a cluster of Fujitsu PRIMERGY servers equipped with NVIDIA H100 Tensor Core GPUs, demonstrating a 40% reduction in power consumption for AI training and inference compared to traditional data centers.
