Co-Packaged Optics Standards Working Group

The Advanced Photonics Coalition (APC) Co-Packaged Optics (CPO) Standards Working Group unites technology leaders, system architects, and end users to define the next generation of high-performance connectivity. With CPO solutions expected to reach commercial availability within two years, our mission is to deliver a set of clear, practical standards that ensure interoperability, accelerate adoption, and enable innovation across a wide range of markets.

​

Our scope includes hardware, software, laser specifics, management frameworks, and system-level integration. In particular, software management is a cornerstone of this work, ensuring that CPO systems can be monitored, controlled, and scaled consistently across multi-vendor environments.  Another key focus is enabling scale-up architectures, such as 72 GPU clusters and beyond, to meet the growing performance and efficiency demands of AI, cloud, and data center environments.   

​

The APC CPO group is aligning with multiple open-source and industry-driven solutions, including Common Management Interface Specification (CMIS), YANG models, OpenConfig, NetConf, RESTConf, and other emerging frameworks. By defining how these tools apply to CPO, APC aims to simplify integration, streamline operations, and promote cross-industry interoperability.

 

By building a full ecosystem of APC member companies—from component suppliers to system integrators and end users—the APC CPO working group ensures that standards reflect the needs of the entire value chain.​​​

The Advantages of Co-Packaged Optics Include:

  • Higher bandwidth density for AI, cloud, and high-performance computing

  • Lower power consumption and improved energy efficiency

  • Greater scalability to support 72+ GPU clusters and future architectures

  • Open-source aligned management frameworks for interoperability and ease of deployment

  • Improved reliability and thermal performance

  • Cross-vendor interoperability, reducing fragmentation and accelerating adoption

  • Demonstrate solutions utilizing the current model of APC Silicon Photonics and CPO ecosystem 

​

This work benefits industries such as medical technology, defense, enterprise IT, and financial institutions—markets where low latency, reliability, and energy efficiency are mission-critical.​​​​
