In Depth

Key Findings

Credo has announced the completion of its acquisition of DustPhotonics, a specialist in optical interconnect technology. This strategic acquisition is expected to significantly enhance Credo’s Co-Packaged Optics (CPO) solutions and accelerate the development of high-bandwidth, low-power interconnect technologies for AI data centers.

Technical Details

DustPhotonics excels in the development of high-performance silicon photonics technology, particularly optical engines and optical transceivers. The integration of Credo’s industry-leading SerDes (serializer/deserializer) and DSP (digital signal processor) technologies with DustPhotonics’ optical expertise will elevate CPO solutions to a new level. CPO is a technology that tightly integrates switch ASICs (Application-Specific Integrated Circuits) and optical engines within the same package. Compared to traditional electrical connections via PCBs (Printed Circuit Boards), CPO minimizes signal loss and significantly reduces power consumption. This enables scalable and energy-efficient interconnects necessary for next-generation data transmission speeds of 400G, 800G, and even 1.6T.

Background and Context

The explosive growth of AI and high-performance computing (HPC) workloads has placed unprecedented demands on data center network infrastructure. Especially in the training and inference of large-scale AI models, vast amounts of data must move at high speeds between chips, and existing electrical interconnects have become bandwidth and power efficiency bottlenecks. CPO technology is garnering significant attention as one of the most promising solutions to address this challenge, and its adoption is accelerating across the industry. As evidenced by Marvell’s announcement of the industry’s first 102.4 Tbps AI switch, data center bandwidth requirements are increasing exponentially, and CPO is an indispensable technology for meeting these demands.

Strategic Significance and Outlook

Credo’s acquisition of DustPhotonics is expected to further accelerate the growth of the co-packaged optics market in AI data centers. The integrated technology stack will enable the construction of higher-performance and more energy-efficient AI infrastructure, contributing to reduced operating costs and improved sustainability for data centers. This acquisition is a crucial step in shaping the future of data center networking in the AI era and is expected to significantly impact the development of next-generation AI accelerators, switches, and co-packaged optics modules.
