As data center ethernet switches scale towards 100Tbps, fiber links that keep pace with interconnecting exploding DCI capacity will face significant cost, power and engineering barriers. In this talk, we describe FRESCO, an approach to bring highly coherent WDM Terabit links inside the data center without the need for DSPs and other power consuming technologies. FRESCO is based on photonic integrated ultra-stable, ultra-low linewidth shared laser, optical frequency comb and silicon photonic transceiver technologies.
