System-Level AI Scaling and the Scale-Across Revolution

The architecture of artificial intelligence infrastructure is undergoing a fundamental paradigm shift, moving from component-level enhancement to comprehensive system-level scaling. Historically, performance improvements in high-performance computing relied on localized upgrades — increasing single-GPU compute density or raising individual transceiver lane speeds. However, the emergence of multi-modal, agentic AI systems and Mixture of Experts architectures has pushed compute demands far beyond the physical boundaries of any single accelerator or server chassis. Today, scaling must operate across thousands of synchronized processing units, transforming massive clusters of accelerators into unified logical compute elements.

To support this orchestrated compute environment, data center networks are now structured across three distinct scaling planes. Within the rack, scale-up networks establish ultra-low-latency pathways connecting processors, accelerators, and memory pools. Across the cluster, scale-out networks form the backend switching fabric connecting thousands of individual server nodes. Beyond any single physical data center, scale-across architectures link geographically distributed facilities together — driven by severe localized power grid limitations and physical space constraints, forcing operators to deploy dozens or hundreds of fiber rails over distances of thousands of kilometers.

Operating at this geographic scale pushes optical transmission networks against the Shannon limit, which defines the absolute maximum capacity of a fiber channel. As traditional data center interconnects exhaust the capacity of the C+L band spectrum, deploying multi-rail optical solutions has transitioned from a progressive design choice to an operational necessity. Modern hyperscale deployments, exemplified by CoreWeave’s specialized AI facilities, deploy NVIDIA Quantum InfiniBand fabrics capable of delivering non-blocking bandwidth of up to 3,200 Gbps per node across clusters containing more than 100,000 GPUs.

The Physical Boundaries of 224G PAM4 and the Copper-to-Optics Frontier

As next-generation AI fabrics transition to 1.6T and 3.2T Ethernet speeds, physical layer signaling must double from 112G to 224G per lane. This doubling of lane speeds exposes severe physical limits in traditional transmission media, causing standard printed circuit board materials like FR4 to act as aggressive low-pass filters. At 224 Gbps, the Nyquist fundamental frequency jumps to an unprecedented 56 GHz, where even minor impedance mismatches or physical package tolerances generate catastrophic insertion loss, signal reflections, and high-frequency ripples.

To double the data rate within these tight physical boundaries, the industry relies on PAM4 modulation, which sacrifices approximately 9.6 dB of Signal-to-Noise Ratio compared to legacy NRZ signaling. Consequently, at 224G, bit errors are a continuous, expected physical reality rather than a rare anomaly. If the pre-Forward Error Correction Bit Error Rate exceeds critical thresholds, the system breaches the “FEC cliff,” resulting in uncorrectable codewords, dropped Ethernet frames, and severe packet retransmission delays that spike RoCEv2 latency and degrade overall GPU cluster stability.

This physical signaling degradation has fundamentally altered the transmission reach of copper. While passive copper Direct Attach Cables supported reaches up to 2.5 meters at 112G, their reach collapses to approximately 1 meter at 224G, restricting passive copper solely to intra-rack server tray connections. To address this limitation, system designers must deploy a diverse array of active copper and optical interconnect technologies, balancing trade-offs across power, latency, reach, and manufacturing complexity.

The High-Speed Connectivity Battleground: Broadcom, Marvell, Astera, and Credo

Broadcom Inc.

Broadcom maintains a dominant position in high-bandwidth physical layer digital signal processors and high-end optical components, leveraging its massive manufacturing scale and deep IP portfolio. To address the power and cost challenges of 1.6T and 800G links, Broadcom has systematically expanded its 200G-per-lane DSP family. The Sian3 represents a state-of-the-art 3nm, 200G-per-lane PAM4 DSP engineered for single-mode fiber applications, enabling over 20% power reduction for electro-absorption modulated laser and silicon photonics based modules to deliver sub-23W 1.6T transceivers. Broadcom’s competitive advantage lies in its monolithic integration of advanced DSPs with its proprietary 200G VCSEL and EML laser technologies, allowing the company to capture high margins across both optical silicon and discrete laser markets.

Marvell Technology, Inc.

Marvell is emerging as a comprehensive connectivity architect, reporting record data center revenue of $1.833 billion, up 27% year-over-year, and expecting full-year data center revenue to grow approximately 50%, led by optical interconnect revenue expansion exceeding 70%. The company’s recent acquisition of Celestial AI strategically positions Marvell to move optics closer to compute and address memory constraints through optical memory sharing. To directly challenge Credo’s dominance in the active copper market, Marvell launched its “Golden Cable” initiative — a standardized, validated AEC reference architecture partnered with high-volume manufacturers like Foxconn Interconnect Technology and Luxshare Tech, aiming to commoditize the physical cable assembly layer and squeeze Credo’s hardware margins.

Astera Labs

Astera Labs is a prominent pure-play provider of silicon-based connectivity hardware and software, focusing heavily on scale-up architectures inside the server chassis. Astera has established a strong moat through its Aries PCIe and CXL Smart DSP Retimers, deployed in high volume across NVIDIA’s Hopper and HGX GPU platforms, and holds a first-mover advantage with its Aries 6 retimers — the industry’s only PCIe Gen 6 retimers shipping in high volume. The company’s growth is further supported by its Scorpio X switch, expected to see significant volume ramp in the second half of 2026 to support custom accelerators like the Amazon Trainium 3.

Credo Technology Group FY2026: Revenue Tripled, Margins Held

Operating Results and Profitability

For the full fiscal year 2026, Credo’s total revenue reached $1.335 billion, more than tripling the $436.775 million reported in fiscal 2025. Fourth-quarter revenue climbed to a record $437.003 million, representing 7.4% sequential growth and a 157.0% surge year-over-year, driven by the rapid adoption of its core Active Electrical Cable products in dense AI network architectures. This top-line expansion unlocked significant operating leverage, driving full-year non-GAAP operating margin to 47.8% and non-GAAP net income to $661.543 million, which translates to a non-GAAP diluted EPS of $3.46.

Credo’s gross margin profile remained highly resilient, with GAAP gross margin at 68.2% in Q4 and 68.0% for the full year. Credo maintains these premium margins by designing its high-speed connectivity silicon on mature, cost-effective process nodes such as 12nm, while competitors are forced to fabricate on more expensive 5nm or 3nm nodes. This architecture allows Credo to deliver equivalent electrical performance at structurally lower silicon cost — a durable margin advantage that does not disappear as competitors scale.

Balance Sheet and Capital Allocation

Credo ended fiscal year 2026 with $1.443 billion in total liquid assets, including $1.165 billion in cash and cash equivalents and $278.334 million in short-term investments. The company’s operations are highly cash-generative, delivering $182.2 million in cash flow from operations and $177.5 million in free cash flow during the fourth quarter alone. This capital base provides Credo with the financial flexibility to fund advanced 3nm and 2nm tape-outs and execute strategic acquisitions without relying on external debt or equity dilution.

This cash position was utilized to fund the acquisition of Dust Photonics. The acquisition of Dust Photonics closed in late May 2026, resulting in a net cash outflow of $750 million in the first quarter of fiscal 2027. To preserve its remaining cash buffer for organic growth, Credo has stated it does not plan to raise additional capital or initiate share buyback programs in the near term. To secure leadership stability during this critical growth phase, Credo’s board approved a one-time long-term equity incentive for CEO William Brennan — a 100% performance-based PSU grant of up to 1,437,000 ordinary shares, with vesting tied to revenue targets ranging from $2.5 billion to $7.5 billion and stock price hurdles between $244.70 and $489.40 per share through June 30, 2031.

Silicon Photonics, Dust Photonics, and the Five-Pillar Product Portfolio

The acquisition of Dust Photonics represents a major milestone in Credo’s technology roadmap, designed to address the inevitable physical limits of copper as data rates transition to 1.6T and 3.2T speeds. Dust Photonics is a pioneer in Silicon Photonics Photonic Integrated Circuit technology, which integrates key optical translation and transmission functions onto a single silicon chip. This integration reduces component complexity, improves manufacturing yields, and drives down cost-per-port as networks scale, establishing a clear technological path toward Near Port Optics and Co-Packaged Optics applications.

By integrating Dust Photonics’ SiPho PIC technology with its own SerDes and DSP intellectual property, Credo has established a vertically integrated connectivity stack. This vertical integration allows the company to capture higher margins, shorten product qualification cycles, and eliminate dependencies on external silicon photonics suppliers. The PIC market represents a massive opportunity, projected to reach $6 billion by 2030.

Market Opportunities, Critical Vulnerabilities, and Strategic Imperatives

Key Market Opportunities

The 1.6T transition and collapsing copper reach create a large structural opportunity for active copper solutions. Credo’s PCIe Gen 6 and 1.6T AECs are well-positioned to capture this demand, extending the reach of cost-effective copper cabling up to 7 meters inside and between dense GPU racks, thereby delaying the need for more expensive optical links. Meanwhile, the neocloud ecosystem — led by specialized operators like CoreWeave, TensorWave, and Iris Energy — is rapidly scaling dense GPU clusters that require highly optimized, low-latency fabrics to maximize cluster uptime, representing a major opportunity for Credo to secure high-margin sockets outside of traditional hyperscale accounts.

Management has signaled 80%+ fiscal 2027 revenue growth, with $600 million or more expected from the optical portfolio alone as ZeroFlap optics ramp into production. This optical pivot, enabled by the Dust Photonics silicon photonics foundation, allows Credo to offer a vertically integrated end-to-end electrical and optical connectivity stack — capturing higher margins, simplifying manufacturing, and building a highly defensible IP portfolio.

Strategic Imperatives

• Accelerate Hyperscaler Diversification

  Credo must prioritize onboarding additional Tier 1 hyperscalers and neocloud providers to reduce its dependency on AWS. Leveraging Dust Photonics silicon photonics capabilities to secure optical transceiver and LRO sockets at Google and Microsoft should be the primary strategic sales objective through FY2028, targeting a customer mix where no single account exceeds 30% of total revenue.

• Counter Marvell’s Golden Cable with Manufacturing Partnerships

  To defend against Marvell’s open AEC ecosystem, Credo should form exclusive, long-term manufacturing agreements with leading global electronics manufacturing services providers. Combining its proprietary SerDes IP and automated testing software with high-volume, low-cost assembly partners can protect market share while preserving its gross margin profile.

• Prioritize the Cardinal LRO and ZeroFlap Optical Ramp

  Given the high power and thermal challenges of fully retimed 1.6T optics, Credo should concentrate sales and engineering resources on its Cardinal LRO DSP and ZeroFlap optical platforms. Delivering up to 50% power savings and sub-40ns latency versus fully retimed alternatives provides an optimal balance of cost, power, and multi-vendor interoperability for dense, liquid-cooled GPU clusters.

• Geographically Diversify the Supply Chain

  To mitigate geopolitical and tariff risks, Credo should actively diversify its silicon fabrication, packaging, and optical assembly partnerships outside of the Asia-Pacific region. Establishing manufacturing redundancy in North America or Europe will help secure stable supply chains, comply with tightening government security protocols, and protect customer relationships from geopolitical trade disruptions.
