1Finity, a Fujitsu company, has introduced the Ultra Optical System L1000/L2000 Optical Line System (OLS) platform, which it says is designed to meet next-generation AI networking requirements. 1Finity reports that the open, performance-optimized platform is scheduled to be available in the fall and is intended to serve both hyperscalers and cloud providers building core optical infrastructure and service providers offering high-capacity managed optical services. The company positions it for data center interconnect (DCI), metro, and long-haul transport.
1Finity says the L1000/L2000 is optimized for 800G and higher, using an optimized Direct Attach (DA) architecture intended to support high-capacity transmission and rapid scaling while reducing power and space. The company notes it will be available in multiple shelf sizes and supports both AC and DC power options to fit different operating environments. 1Finity also claims the system “significantly” lowers Total Cost of Ownership (TCO) and adds that its “future-proof” design includes Multi-Rail transmission support for improved long-term power and space efficiency.
For multi-vendor networks, 1Finity says the platform is designed to avoid vendor lock-in and “hidden costs.” It uses a compact, modular architecture that the company says can scale from one to 16 degrees across continuous C+L bands. 1Finity adds that an open Wavelength Selective Switch (WSS) is intended to support Reconfigurable Optical Add-Drop Multiplexer (ROADM) interoperability, with modular building blocks targeted at data center interconnect, metro, and long-haul deployments.
On operations, 1Finity says the L1000/L2000 includes automation features for proactive fiber maintenance, streamlined commissioning, and simplified management, with “glitch-free wavelength scaling across C+L bands.” The company also lists integrated tools for fiber connectivity verification, wavelength design and planning, and diagnostics aimed at proactive maintenance and faster 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.”
1Finity says it will display the platform at MWC Barcelona 2026 (March 2-5) and OFC 2026 (March 15-19) in Los Angeles. The company also reports that L1000/L2000 is associated with a national project on advanced ROADM-based optical networking, citing commissioned research (No.JPJ012368C09001) by Japan’s National Institute of Information and Communications Technology (NICT).
