Japanese comms giant NTT is buying a silicon photonics unit of Fujitsu as part of a key push into OpenRAN and 6G

NTT Electronics is buying 66.6 percent of Fujitsu Advanced Technologies (FATEC), which possesses semiconductor mounting technology for silicon photonics, as part of a key move into 6G and OPenRAN. The new company, now called NTT Electronics Cross Technologies, will start on June 1, 2021.

This is part of the recent IOWN (Innovative Optical and Wireless Network) initiative for 6G.

By the end of 2022, the new company aims to optical communication co-packages that integrate digital chips and COSA (Coherent Optical Sub Assembly) based on silicon photonics technology that will be used in Fujitsu’s 5G basestations with the OpenRAN open standard through operator NTT DoCoMo.

This will allow white box and general-purpose software can be supported in multiple vendor environments, shifting away from the existing, vertically-integrated model that relies on specific vendors. The optical devices will also be based on an open architecture, with products developed by Fujitsu, and control supply chain management. The two partners aim to expand the business globally with a strategic entry into the data centre interconnect market, where demand is expected to grow and the adoption of open architectures is accelerating.

This IOWN approach is also key for 6G says NTT, with research and development now in full swing. Fujitsu says it aims to use the results of the research in manufacturing, distribution, retail, and medical industries.
