All-Photonics Network
As part of this concept, Fujitsu is constructing an All-Photonics Network (APN) that utilizes 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 stringent requirements set by the IOWN Global Forum for Open APN. The system boasts world-class high-capacity transmission capabilities of 1.2 Tbps per optical wave and long-distance transmission at 800 Gbps.
Furthermore, the solution incorporates liquid cooling technology, leading to a remarkable 60 percent reduction in CO2 emissions compared to conventional products. The "1FINITY Ultra Optical System" from Fujitsu is available globally.
