Solving the Interconnect Wall: Redefining Reliability and Serviceability for Next-Generation AI Clusters

As the scale of AI infrastructure clusters shift from thousands to millions of processors, the industry is approaching physical reach limits of traditional electrical signaling. In parallel, pluggable optics fall short of the bandwidth and reliability required for multi-rack scale-up applications for frontier model training and large-scale, long-context inference. At this magnitude, even minor hardware failures can lead to catastrophic system downtime, making system availability the primary metric for operational success. Early testing of co-packaged optics (CPO) show major gains in reliability due to a significant reduction in component count as compared to pluggables. As momentum behind CPO grows, attention has turned to operational issues, particularly how to produce, deploy and maintain these devices at scale.

This presentation addresses the urgent industry need for a shift in how optical connectivity and light sources are managed. Klinger will explore the transition from permanent, fragile fiber attachments to detachable, modular optical interfaces that enable field serviceability and high-yield manufacturing. He will also examine the evolution of light delivery—moving away from discrete, failure-prone laser modules toward software-defined, highly integrated external light engines. By implementing self-healing architectures that can autonomously reroute signals and manage laser redundancy, operators can maintain continuous system operation despite individual component degradation.

Lastly, Klinger will highlight how Lightmatter is uniquely positioned at the intersection of these challenges. By combining the precision of detachable optics with the intelligence of a unique light engine platform, the company provides a holistic solution that delivers the required bandwidth density and reliability, along with high availability at scale.

About the presenter
Prior to joining Lightmatter, Klinger served as a product management, marketing, and applications engineering leader driving the adoption of industry-benchmark processors and networking silicon products utilized by top global equipment OEM’s and hyperscale cloud operators.

His contributions were key to driving the value of two highly successful startups both achieving $billion+ exits, Innovium (cloud datacenter ethernet switch) and Cavium (accelerated networking and security processors). He served as general manager of Cavium’s leading infrastructure processor business. He also held key marketing and applications engineering positions with network processor pioneer AMCC (MMC Networks) and Cypress Semiconductor.

Klinger loves building and motivating teams, creating lasting customer partnerships, and driving breakthrough technologies to deployment. He holds a B.S. in Electrical Engineering from UC Davis.
