According to foreign media reports, NTT (NTT Electronics), a Japanese telephone and telegraph company, acquired Fujitsu’s low-power technology business at a price of 66.6% of FATEC’s shares and established a new company, “NTT Electronics.” NTT Electronics Cross Technologies”, the company will officially open on June 1, 2021.
It is reported that NTT has obtained a license from the local 5G (4.7GHz band) wireless bureau on April 27, local time. NTT and Fujitsu will jointly build a 5G base station based on the OpenRAN (Open Radio Network Interface) open standard, and will implement the IOWN (Innovative Optical and Wireless Network) plan to prepare for 6G research and development. The company designed the ARM processor behind it for the supercomputer Fugaku last year, which was ranked 56th in the world’s top 500 supercomputers in November 2020. Focusing on building a new distributed computing architecture to reduce power consumption, rather than building a more powerful supercomputer, this requires the joint development of ogy by combining photoelectric fusion technology NTT and Fujitsu’s low power consumption technology.
The new company’s goal is to provide compact and energy-saving optical communication collaboration packages for the integration of silicon photonics-based digital chips and coherent photonic components (COSA) by the end of 2022. These chips and components will be used in Fujitsu 5G base stations based on the OpenRAN open standard. The operator of the base station is Japanese telecommunications company NTT DoCoMo.
This means that general software and structural testing of products can be applied to multiple supplier environments in the future without having to rely on the vertical integration model of a specific supplier. At the same time, the optical equipment of the base station will also be based on an open architecture. Fujitsu will develop products and manage the supply chain.
NTT believes that optical communication technology IOWN is a key technology necessary for the development of 6G. It is reported that NTT said that IOWN technology is expected to expand the transmission capacity of optical communication networks by 125 times, reduce end-to-end delay to the current 0.5%, and is expected to reduce energy consumption to the current 1%.
In 2019, NTT, Intel and Sony jointly launched the IOWN Global Forum. NTT proposed a new communication infrastructure that uses cutting-edge optics and information processing technology to provide high-speed broadband communications and huge computing resources. NTT and Fujitsu’s “Smart World”
Cooperation is part of the IOWN plan. This month, the IOWN Global Forum released the “Vision 2030 White Paper”, which mentioned that they will start with the optimization of communication functions and latency, data efficiency, computing scalability and energy efficiency to build the next generation of communication and computing infrastructure.
NTT said that this kind of cooperation is also the key to achieving 6G, and that its 6G research and development work is in full swing.
