NTT has adopted Fujitsu’s 1FINITY Ultra optical transport platform 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.
The 1FINITY Ultra Optical platform leverages an open architecture system that enables flexible network construction. It is anticipated that the system, which will operate nationwide, will deliver transmission speeds of 1.2 Tbps for metropolitan areas such as Tokyo, and transmission speeds at 800 Gbps connecting remote locations, etc., optimized according to the use and the needs of the region.
NTT has proposed its IOWN concept for information and communications infrastructure. To support this concept, Fujitsu is building an All-Photonics Network (APN) that uses photonics in all areas of the communications network. APN features large capacity transmission, diminished delay, and low power consumption which greatly exceeds conventional communication technologies and will be used for the next optical core network which NTT Group will start to construct nationwide.
Fujitsu’s “1FINITY Ultra Optical System” meets the specifications required by the IOWN Global Forum for Open APN and can provide optimum solutions such as world-class high-capacity transmission of 1.2 Tbps per optical wave and long-distance transmission at 800 Gbps. In a world-first, the optical transmission equipment also uses liquid cooling to reduce CO2 emissions from the entire system by 60% compared to conventional products. Fujitsu is offering the “1FINITY Ultra Optical System” globally.
