Overview

Credo Technology Group announced its participation in the Open Co-packaged Interface Multi-Source Agreement (Open CPX MSA) to support the development of interoperable near-packaged and Co-Packaged Optics (CPO) optical interconnect architectures for next-generation AI infrastructure. The Open CPX MSA is defining open specifications for high-speed, high-density connections between ASICs and NPO/CPO. Credo’s involvement will contribute to the standardization and ecosystem expansion of optical interconnects in AI data centers.

In Depth

Key Findings

Credo Technology Group announced its membership in the Open Co-packaged Interface Multi-Source Agreement (Open CPX MSA), committing to contribute to the standardization and development of interoperable near-packaged and Co-Packaged Optics (CPO) optical interconnect architectures. This move is critical for next-generation AI infrastructure and reflects the industry’s recognition of the importance of open technical specifications in addressing bandwidth and power efficiency challenges in AI data centers.

Technical / Clinical Details

The Open CPX MSA aims to define open specifications for achieving high-speed, high-density connections between Application-Specific Integrated Circuits (ASICs), used in AI accelerators and network switches, and optical engines in Near-Packaged Optics (NPO) or Co-Packaged Optics (CPO) configurations. Credo Technology Group brings extensive expertise in high-performance SerDes (Serializer/Deserializer) technology, which will be instrumental in optimizing the interface between electrical and optical signals within the MSA. The focus areas include maintaining signal integrity during data transmission from ASICs to NPO/CPO, achieving high data rates at low power, and ensuring compatibility between components from different vendors. This approach allows data center operators to build AI infrastructure efficiently by selecting optimal components from a flexible supply chain.

Background & Context

The exponential growth of AI workloads places unprecedented demands on data center interconnects, pushing the limits of traditional pluggable optical modules. Specifically, ultra-high-speed and low-latency data transfer within GPU clusters are essential, necessitating technologies like NPO and CPO that bring optical engines physically closer to the ASICs. However, for these new packaging technologies to gain widespread adoption, open standard specifications are crucial to ensure that chips and optical engines from different vendors can reliably interoperate. The Open CPX MSA is a key organization driving this standardization, and the participation of major interconnect technology providers like Credo will accelerate the rapid maturation and broad adoption of the CPO ecosystem.

Strategic Significance & Outlook

Credo Technology Group’s participation in the Open CPX MSA is set to accelerate the evolution of optical interconnects in AI data centers. The establishment of open standard specifications will foster innovation in CPO technology and enhance cost-efficiency and supply stability by ensuring supply chain diversity. This will enable data center operators to deploy higher-performance, more energy-efficient AI infrastructure more rapidly, supporting the further advancement of AI. With leading companies like Credo actively involved, AI-era data center networking is poised to move towards a future of greater interoperability and scalability.
