1Finity Unveils Next-generation Optical Line System for the AI Era and Beyond

New Ultra Optical System open optical line system (OLS) delivers optimized managed fiber services from a simple design that fits anywhere

KAWASAKI, Japan–(BUSINESS WIRE)–#AI—1Finity, a Fujitsu company and leading provider of global network solutions, today introduced the Ultra Optical System L1000/L2000 Optical Line System (OLS) platform to address next-generation AI networking needs. This open, performance-optimized global platform, to be available in the Fall of this year, provides both core optical infrastructure for hyperscalers and cloud providers, and enables service providers to offer high-capacity managed optical services to their customers. These dual applications ensure high-capacity, peak performance, and reliable scalability for DCI, metro, and long-haul transport.

Achieving a strategic advantage in meeting AI service demands requires communication service providers, hyperscalers, and cloud providers to adopt line systems optimized for 800G and beyond. The L1000/L2000 is a next-generation platform, purpose-built with an optimized Direct Attach (DA) architecture for high-capacity service transmission and rapid scaling while reducing power and space. Available in various shelf sizes with AC and DC power, it offers unmatched flexibility for any operating environment. This system guarantees reliable 800G and higher speeds, significantly lowering Total Cost of Ownership (TCO). Its future-proof design includes Multi-Rail transmission support, ensuring even greater long-term power and space efficiency.

Designed for multi-vendor operation, the L1000/L2000 OLS platform eliminates vendor lock-in and hidden costs. Its flexible, compact, modular architecture scales from 1 to 16 degrees across continuous C+L bands. An open WSS (Wavelength Selective Switch) ensures seamless operation for ROADM interoperability, which provides significant cost reduction and greater network element selection, utilizing modular building blocks for data center interconnect, metro, and long-haul networks.

The L1000/L2000 OLS platform leverages advanced automation for proactive fiber maintenance, streamlined commissioning, and simplified management. It achieves smooth, glitch-free wavelength scaling across C+L bands. Integrated tools enable fiber connectivity verification, optimized wavelength design/planning, and deep diagnostics for proactive maintenance and swift resolution of fiber issues.

“The Ultra Optical System L1000/L2000 OLS empowers CSPs, Hyperscalers, and Cloud providers to reliably deliver optimized, managed fiber services and core optical infrastructure from the same simple, compact design that fits anywhere,” said Hideki Matsui, SVP, Head of Photonics System Business Unit at 1Finity Inc. “Providing open, performance-optimized and reliable connectivity, this next-generation optical line system ensures a scalable foundation for evolving network demands, empowering growth for the AI era and beyond.”

The platform will be displayed at MWC Barcelona 2026, to be held March 2-5, and OFC 2026, March 15-19, in Los Angeles.

L1000/L2000 is associated with a national project focused on advanced ROADM-based optical networking. These research results were obtained from the commissioned research (No.JPJ012368C09001) by National Institute of Information and Communications Technology (NICT), Japan.
