NTT selects Fujitsu’s solution for Japan’s next-generation optical core network
Fujitsu announced that NTT Corporation has adopted Fujitsu’s optical transport platform ‘1FINITY Ultra Optical System’ as a verification system for use in trials ahead of the construction of the next optical core network covering Japan. Fujitsu received the system order in June 2023 and will deliver it in the first half of fiscal 2023.
Fujitsu will contribute to the establishment of an optical core network for NTT and its group companies. By adopting Fujitsu’s technology, NTT aims to address societal challenges and work towards achieving carbon neutrality by reducing power consumption.
Advancing the IOWN concept
The initiative aligns with NTT Group’s concept of innovative optical and wireless network (IOWN), which seeks to enhance existing information and communications systems by developing new infrastructure.
All-photonics network
As part of this concept, Fujitsu is constructing an all-photonics network (APN) that utilises photonics across the entire communications network. The APN offers enhanced transmission capacity, reduced latency, and lower power consumption compared to traditional communication technologies, making it an ideal solution for NTT’s next optical core network deployment nationwide.
Fujitsu says its ‘1FINITY Ultra Optical System’ meets the specifications required by the IOWN Global Forum for open APN. The system boasts high-capacity transmission capabilities of 1.2 Tbps per optical wave and long-distance transmission at 800 Gbps.
Fujitsu’s 1FINITY Ultra Optical System
As NTT’s development partner, Fujitsu will provide the ‘1FINITY Ultra Optical System,’ a highly flexible and open architecture system with features such as high-capacity transmission, low latency, and low power consumption. The system is expected to achieve transmission speeds of 1.2 Tbps in metropolitan areas like Tokyo and 800 Gbps for connecting remote locations, catering to the specific needs and requirements of each region.
