SoftBank today announced that it has successfully completed nationwide deployment of an all-optical network across key areas in Japan using a disaggregated architecture optical transmission system that supports open networks, comprising Fujitsu's next-generation optical transmission platform '1 FINITY Ultra Optical System T900'. Through this initiative, Fujitsu and SoftBank aim to contribute to the realization of greener networks by building communication infrastructure with a lower environmental impact.
The all-optical network uses optical technology in all areas of the communications network. The new network realizes a reduction of power consumption of up to 90% compared to previous networks, by connecting to equipment compatible with all-optical technology and applying liquid cooling technology.
Using a pair of optical fibers, Fujitsu and SoftBank further improved communication performance, achieving high capacity and high-speed transmission of up to 48.8Tbps (approximately twice as high as that of conventional networks).
With the introduction of the new optical transmission system, SoftBank aims to build a network that achieves carbon neutrality while meeting the ever-increasing demand for data communication in anticipation of future networks based on Beyond 5G/6G technology.
