As artificial intelligence workloads continue to demand unprecedented bandwidth, the architecture connecting global cloud infrastructures is undergoing a massive transformation. Leading the charge in data infrastructure semiconductor solutions, Marvell Technology, Inc. (NASDAQ: MRVL) has announced a groundbreaking expansion of its coherent DSP and pluggable portfolio.
The company has introduced the industry’s first 1.6T ZR/ZR+ data center interconnect (DCI) pluggable alongside a new generation of 2nm coherent DSPs featuring built-in media access control security (MACsec). For enterprise IT professionals and network architects following the latest hardware shifts here at AarokaTech, these new modules represent a critical leap forward in secure, high-speed DCI networking.
The Growing Demand for Hyperscale DCI
The rapid acceleration of distributed AI workloads is driving an exponential increase in traffic between data centers. To keep pace, modern networks require connectivity solutions that deliver maximum bandwidth with minimal power consumption and robust built-in security.
Industry analysts project that the demand for coherent pluggables will surge dramatically through 2030. However, producing this highly specialized technology at scale requires immense manufacturing capabilities. Marvell is leveraging its robust production pipeline to deliver the high-volume yields necessary to supply the world’s largest hyperscale and cloud data centers.
Scott Wilkinson, lead analyst at Cignal AI, highlighted the competitive nature of this space: “The size of the pluggable coherent market is massive but increasingly competitive. Maintaining leadership requires power efficiency, critical features and high-volume manufacturability. Marvell has a proven track record… and the company’s move to 2nm solutions underscores its commitment to density, performance and power.”
Introducing the COLORZ 1600 and Electra DSP
At the heart of Marvell’s announcement is the COLORZ 1600, the industry’s first 1.6T ZR/ZR+ pluggable. This powerhouse is driven by the Marvell Electra, the world’s first 2nm 1.6T ZR/ZR+ coherent DSP.
Key capabilities of the COLORZ 1600 include:
- Versatile Reach: Seamlessly connects campus (20km), metro (120km), and regional (1,000km) data centers operating at 1.6T.
- Embedded Security: Features in-chip MACsec security to protect data in transit.
- Broad Compatibility: Delivers full interoperability across OpenZR+, OIF, and OpenROADM modes.
- Form Factor: Available in the OSFP form factor, supporting both C and L bands while drastically reducing power consumption per bit compared to legacy systems.
Scaling at 800G with COLORZ 800 and Libra DSP
Alongside the 1.6T flagship, Marvell also introduced the Libra—the industry’s first 2nm 800G ZR/ZR+ coherent DSP. This chip powers the second-generation COLORZ 800 pluggable, offering cloud operators a highly efficient, lower-power solution to securely scale their interconnects.
Key capabilities of the COLORZ 800 include:
- Extended Range: Achieves up to 1,000km at 800G for metro data centers, 2,000km at 600G, and an impressive 3,000km at 400G for regional deployments.
- Cost Efficiency: Significantly lowers DCI capital expenditures when compared to traditional, bulky optical transport systems.
- Flexible Deployment: Available in QSFP-DD or OSFP form factors (C and L bands) with full interoperability.
Manufacturing Scale and Future Availability
Innovation in the lab must be matched by execution on the production floor. Russ Esmacher, Senior VP and GM of Data Center Interconnect at Marvell, emphasized this dual focus: “Meeting the global needs of AI-driven data centers requires proven, large-scale manufacturing strength, from resource planning to test capacity. We are expanding our pluggable manufacturing capacity to help customers rapidly deploy the latest disruptive technologies.”
Industry professionals looking to deploy these technologies can expect Marvell to begin sampling the Electra and Libra DSPs, along with the COLORZ 1600 and 800 pluggables, to customers in the second half of 2026. Furthermore, Marvell will be showcasing its end-to-end connectivity portfolio at OFC 2026 (March 15–19) at the Los Angeles Convention Center (Booth #1600).
