OFC: Lumentum Optical Circuit Switching and Marvell Optics for Scaling AI
By Todd Rope, Vice President of Software Engineering at Marvell
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.

Live from OFC: Pioneering a New Class of Interconnects—Hybrid AEC/ACC Cables—for Optimizing Infrastructure
By Nicola Bramante, Senior Principal Engineer, Connectivity Marketing, Marvell
Why develop a hybrid cable? Because the quest for greater optimization in AI data centers never ends.
High speed cable developer and manufacturer Luxshare-Tech and Marvell showed off the industry’s first hybrid AEC/ACC solution at OFC 2026, the latest step in enhancing copper interconnects to meet the stringent power, performance and reach standards of AI infrastructure.
Active electrical cables (AECs) are designed for comparatively long (~4-9 meter) high-bandwidth connections within or between racks. The boost in reach over passive copper cables is accomplished by integrating optimized AEC DSPs into the terminal ends of a cable. Active Copper Cables (ACCs), by contrast, rely on equalizers and redrivers for extending reach. ACCs consume far less power than AECs but generally are deployed for in-rack connections running 2 meters or less.
Hybrid AEC/ACC cables combine technologies from both for a solution that delivers a longer, AEC-like reach and the low latency, low power, low cost and low complexity benefits of ACC designs.

Six Lessons I Learned from Six Roles at Marvell
By Diana Sandu, Packaging Engineering Manager, Marvell
1. Step Outside Your Comfort Zone
I joined Marvell through the Inphi acquisition back in 2021 during my fourth year of my BSc program. I studied Electrical Engineering and Applied Electronics at the University POLITEHNICA of Bucharest. Before joining, I wasn't familiar with Marvell or any other semiconductor companies, nor did I have any background in packaging design. When a friend of mine, who had previously interned at Marvell, told me about the internship, I decided to apply.
2. Don’t Be Afraid to Try
A few months into the internship, a 6-month program, one of the projects I was working on with two other interns was sold to a client, which meant we then worked on a tight schedule solving challenging technical issues in real time. We were working on a design for 5G communication, using 2.5D Packaging, which includes the interposer. The project taught me so much about layout and packaging design and helped me gain the skills I needed. During the project, I became a full-time employee as a Junior Packaging and Signal Integrity Engineer.

The Golden Cable Initiative: Enabling the Cable Partner Ecosystem at Hyperscale Speed
By Michael Arsenault, Director of Product Marketing for AEC DSPs, Marvell
Rack connectivity is undergoing a historic transformation. Data center operators are demanding both scale-up and scale-out connectivity that can move more data across longer distances and between more systems, while delivering unprecedented levels of energy efficiency and reliability.
To help cable providers and their customers meet these challenges, Marvell has launched the Golden Cable initiative, designed to accelerate the development of active electrical cables (AECs). AECs are a rapidly growing class of high-bandwidth, enhanced copper interconnects used to link servers, switches, NICs and other assets in the same rack or across adjacent racks (about two to nine meters).
The Golden Cable initiative delivers a validated cable architecture tested across leading platforms and built on industry-leading software, reference designs, technical data, firmware and comprehensive support. Participants can combine these assets with their own technology to develop unique AECs powered by DSPs, optimized for specific customer requirements and use cases.
To further enhance performance and ensure broad compatibility, Golden Cable AECs are rigorously tested in the Marvell Cloud Interoperability Lab. Here, cables are validated across a wide range of customized configuration scenarios involving leading XPUs, CPUs, NICs, servers, switches, optical modules and other critical infrastructure components. This process enables Marvell and its partners to validate AEC firmware before cables reach end-customers, significantly accelerating customer qualification and deployment timelines. The result is greater confidence from the first plug-in.

Marvell Named to America’s Best Midsize Employers 2026 Ranking
By Vienna Alexander, Marketing Content Professional, Marvell
In a recent Forbes and Statista ranking, Marvell was named as one of America’s Best Midsize Employers for 2026.
The America’s Best Employers ranking, now in its eleventh year, recognizes organizations that have demonstrated an outstanding commitment to fostering collaborative workplaces. To present the ranking, Forbes partnered with established market research firm Statista.
The list is based on over 217,000 U.S. employee independent survey responses from companies with a national workforce of at least 1,000 people. To further categorize the results, companies with between 1,000 and 5,000 employees were deemed midsized, while companies with more than 5,000 people were referred to as large employers. The survey evaluates areas of Atmosphere and Development; Salary and Wage; Company Image; Culture; Working Conditions; and Workplace Environment.
