In this presentation we discuss the future of multimode links for datacenters. We begin by highlighting an often ignored but proven fact that for short reaches, VCSEL-based optical transceivers are the most cost-effective and energy-efficient solution. But as data rates increase to keep up with bandwidth growth, can multimode transceivers maintain their value in data centers? The answer is a resounding “yes”. Recent demonstrations and standards-development work suggest that 100G-per-lane VCSELs will enable three short-reach data center applications in the near future – server connectivity, switch connectivity, and connectivity for an emerging class of systems aimed at machine learning and high-performance computing.
