Data Center Networks & High Rate Transponders

Tutorial - We.B.1.T Future Optical Data Center Networks

Chongjin Xie Alibaba Group Abstract With the widespread use of cloud computing and internet services, data centers have become the infrastructure of digital economy and the main driving force for optical networks technologies in recent years. In this tutorial, we first present the characteristics and requirements of optical data center networks, then technologies for scaling optical data center networks are described, including data center network architectures, high-speed embedded coherent and simple pluggable coherent technologies, technologies to build open and disaggregated optical networks, network automation and intelligence, etc. Challenges and potential technologies to further scale optical data center networks are discussed at the end.
