Lightwave Fabrics: At-Scale Optical Circuit Switching for Datacenter and Machine Learning Systems

Abstract
We describe our experience developing what we believe to be the world’s first large-scale production deployments of lightwave fabrics used for both datacenter networking and machine-learning applications. Optical circuit switches and optical transceivers developed in-house have produced a lightwave fabric that is reconfigurable, low latency, rate agnostic, and highly available. These fabrics have provided substantial benefits for long-lived traffic patterns in tightly-coupled machine learning clusters. We also report results for a large-scale ML superpod with 4096 tensor processing unit chips that has more than one exaflop of computing power.
