Optical circuit switching (OCS) has become one of the fastest growing segments in networking with revenue expected to exceed $3.5 billion by 2029, more than 2x over 2025.1 The unique architecture of OCS systems, however, also mean that developers and data center operators need to ensure that these systems can seamlessly integrate into data infrastructure and interoperate with existing product lines.
Lumentum and Marvell took a significant step toward that goal with a live demonstration at OFC 2026 that combined the R300 OCS system from Lumentum with different classes of modules powered by Marvell optical DSPs. The modules included inside-the-data center modules powered by the Marvell® Ara 1.6T (5m-2km interconnects), coherent lite modules with 1.6T Marvell Aquila for campus-size connections (2 to 20km) and long-range COLORZ® 800T ZR/ZR+ modules for 10-1000km data center interconnects.
Marvell RELIANT™, a new software platform for analyzing equipment performance and optimizing networks in real-time, was also used to monitor data transmission, power consumption, bit error rate and other metrics in the demo. Michael DeMerchant, senior director of product line management at Lumentum and I walk you through more of what RELIANT can accomplish with OCS in the video.
Networking is in the midst of a fundamental transformation due to the performance demands of AI. Developing and deploying systems that can deliver on everything that hyperscalers need—higher bandwidth, greater efficiency, lower latency, longer interconnects, greater security, higher reliability—will require cooperation across an extensive ecosystem of partners. Expect to see more collaborative efforts like this from Marvell as we seek to expand the possibilities of AI infrastructure.
