Fujitsu Limited has announced the launch of a new wholly owned subsidiary, 1FINITY Inc., to consolidate its network products business and strengthen its presence in the global telecommunications market. Scheduled to begin operations on July 1, 2025, the new company will focus on advancing optical and mobile systems, expanding into AI-driven data center infrastructure, and contributing to next-generation communications such as 6G and IOWN.
As part of its 2023 Medium-Term Management Plan, Fujitsu is reorganizing to drive sustainable growth and enhanced profitability. The creation of 1FINITY aligns with Fujitsu’s broader transformation into a technology company delivering digital services with net positive societal impact. The transfer will bring together development, sales, support, and maintenance of key technologies including O-RAN-compliant 5G equipment, photonics, and Virtuora network software under one agile and focused organization.
The initiative will integrate four Group companies—Fujitsu Telecom Networks, Fujitsu Network Service Engineering, Mobile Techno Corporation, and Fujitsu Network Communications (U.S.)—into 1FINITY. The new unit will be led by Masaaki Moribayashi, with headquarters at Fujitsu Technology Park in Kawasaki, and approximately 1,800 employees (4,600 including subsidiaries).

Fujitsu’s 1FINITY product portfolio currently includes modular, disaggregated optical and packet networking solutions designed to meet the evolving demands of modern telecommunications networks. This architecture emphasizes scalability, flexibility, and efficiency, catering to applications ranging from metro and regional networks to long-haul and data center interconnects.
Key Components of the 1FINITY Portfolio:
- 1FINITY Ultra Optical System: This system integrates advanced ROADM and transponder technologies, offering terabit-scale optical networking. Features include up to 1.2 Tbps per wavelength, continuous C+L band support, forward Raman amplification, and AI/ML-driven automation for streamlined operations and enhanced sustainability.
- 1FINITY P300 Coherent Pluggable Transceiver: The P300 is an 800G ZR/ZR+ coherent pluggable transceiver that enables flexible deployment options. It supports integration with Fujitsu’s edge networking portfolio, 1FINITY T-series transponders, third-party routers, and line systems like the 1FINITY L100 and L900. The P300 offers 30% power-per-bit savings and is designed for scalability up to 1.6 Tbps.
- 1FINITY T-Series Transponders: These transponders, including models like the T900 and T950, deliver high-capacity transport solutions. The T900, for instance, offers 1.2 Tbps long-haul transport performance, making it suitable for data center interconnect and backbone network applications.
- 1FINITY L-Series Open Line Systems (OLS): The L-Series, such as the L900, provides scalable and flexible ROADM functionality. The L900 features a 2×32 continuous C+L-band ROADM-on-a-blade, supporting high-capacity optical networking with a compact footprint.
- 1FINITY S-Series Switches: The S-Series includes switches like the S900 and S100, offering Layer 2 Ethernet aggregation and switching capabilities. The S900 provides 120 Gb of bidirectional packet switching capacity in a 1RU form factor, ideal for networks requiring 1 Gb to 10 Gb aggregation. The S100 offers high-density packet optical MEF Carrier Ethernet operation, supporting various topologies and service interfaces.
- 1FINITY L100 Series: This series offers flexible ROADM functionality with a modular design, accommodating rapid bandwidth growth. Blades like the L100, L110, and L120 provide building blocks for scalable ROADM architectures, supporting multi-degree, flexible-grid operation and super-channel support.
