SC461 - High-capacity Data Center Interconnects

Monday, 04 March
09:00 - 12:00

Short Course Level: Beginner


Dirk van den Borne; Juniper Networks, Germany
Sander L. Jansen; ADVA Optical Networking, Germany

Short Course Description:

This short course gives a broad overview of data center interconnect (DCI) architectures and technology, ranging from short-haul interconnects of just a few kilometers across a campus network, to metro and finally long-haul deployments. It will cover the latest optical technology developments and how these are used to build ever denser, more power efficient, higher capacity and more scalable data center interconnect links.

We will provide an overview of the different technologies that are most relevant for today’s data center interconnects, covering the full range of transmitter and receiver technologies, pluggable form factors, modulation formats, protocols and data rates. In addition, we will also cover system design aspects such as open line systems, disaggregation of the optical layer and encryption. We will discuss in detail what makes data center interconnects different from traditional optical transport networks, and what are the most relevant design criteria in today’s DCI deployments. Finally, we will cover in detail the latest standardization activities as well as research and development directions towards future architectures.

The short course should enable attendees to obtain a detailed overview of the different technologies and architectures that are most relevant to wide area data center interconnects and get a comprehensive understanding for the different system design trade-offs in terms of cost, capacity, density, power consumption and complexity.

Short Course Benefits:

This course should enable you to:

  • Describe the typical requirements addressed by data center interconnects, such as transmission distances, system capacity, traffic profiles, data rates, protocols and transmission latency.

  • Understand the typical system architecture of today’s data center interconnects, and which architectures are typically deployed in enterprise, Tier-2/3 and cloud scale data center deployments.

  • List different flavors of suitable modulation formats and detail the advantages and disadvantages of each method with respect to optical performance and power efficiency.

  • Understand the different transceiver architectures in the context of short-reach DCI, for example direct detection in comparison to coherent detection, and how to leverage the trade-off between optical performance and system complexity / cost.

  • List the trade-offs in terms of digital signal processing for different transceiver architectures, and the impact this has on power consumption, complexity and system capacity.

  • Illustrate relevant developments in terms of optical components such as silicon photonics to provide denser integration and more cost-effective transceiver architectures.

  • Understand future directions in research and development as well as fundamental technology limits of data center interconnects.

  • Obtain an overview of the different standardization bodies and activities relevant for data center interconnects such as IEEE, OIF and TIP.

Short Course Audience:

This course is intended for engineers, researchers and technical managers who would like to gain a better understanding of data center interconnect technology, architectures and solutions. Practical network implementations and system design trade-offs will be discussed in detail, such that the participants can obtain a good level of understanding for the challenges of today’s data center interconnect solutions. Participants should have a comprehensive knowledge in the field of fiber-optic transmission systems; no previous knowledge of data center architectures is required.

Instructor Biography:

Dirk van den Borne received his Ph.D. degree in electric engineering from the Eindhoven University of Technology, The Netherlands. During his Ph.D. research, he succeeded in the first-ever demonstration of 100G modulation and detection with coherent detection and digital signal processing, now the established industry standard for 100G transport. In 2008, he joined Nokia Siemens Networks where he was responsible for the optical system performance of the DWDM transport systems. Since 2012 he works at Juniper Networks, where he is a director of architecture and advises service providers worldwide on their network evolution strategy. Dr. van den Borne has spoken frequently at major industry events, authored and co-authored more than 100 peer-reviewed papers and conference contributions and holds several patents on optical communication. He is an associate editor for PTL and served on various technical program committees.

Sander L. Jansen received his Ph.D. degree (with highest honors) in EE from the Eindhoven, University of Technology. Subsequently, Dr. Jansen worked as a post-doc at KDDI R&D Laboratories in Japan where he specialized in optical orthogonal frequency division multiplexing (OFDM). From 2008 to 2012 he was project manager at Nokia Siemens Networks in Germany. Currently, Dr. Jansen is Director of Product Line Management at ADVA Optical Networking, Germany. Dr. Jansen authored and co-authored 10+ patents, one book chapter and more than 100 refereed papers and conference contributions. He is a senior editor for PTL and has served as a committee member on various conferences. He has received several awards including the Young Investigator award from the IEEE Photonics Society “for pioneering contributions in optical OFDM for fiber-optic transmission systems”.
