Short Course Level: Advanced Beginner

Short Course Description:

The increasing demand for data and video-intensive content and the adoption of cloud services are driving needs for ever increasing capacity in service provider’s backbone and metro networks while also creating needs for high speed interconnect of hyper-scale data centers. To satisfy the growth in demand for bandwidth, communication and content service providers are deploying 100Gb/s throughout their networks today, and are increasingly planning to deploy even higher speeds, e.g. 400Gb/s and beyond, on shorter high capacity links. We are also seeing a trend toward flex-rate systems where transmission speeds and capacity can be optimized for a given fiber distance.

The first part of this course provides an overview of the drivers and applications of 400Gb/s transmission systems in data center and Service Provider networks. It describes the requirements and expectations Network Operators will have to cost, power consumption, footprint, reliability, optical performance, and interoperability. We present practical design issues of 400Gb/s pluggables and line-cards, and we critically review the availability and performance of the key building blocks. In particular, we discuss the technologies needed to implement different modulation formats, and the corresponding trade-off between complexity/cost of line-card implementations and the achievable fiber transmission distance. We also look at future bitrates and technologies beyond 400Gb/s, including configurable flex-rate systems where transmission speeds and capacity can be optimized for a given fiber distance.

Short Course Benefits:

This course should enable you to:

  • Identify key requirements and drivers for 400Gb/s applications

  • Understand key building blocks of coherent systems

  • Describe the availability and performance of 400Gb/s.

  • Discuss 400Gb/s transmission limitations

  • Summarize 400Gb/s standards activities

  • Describe drivers and technologies for systems beyond 400Gb/s

  • Understand applications of flex rate systems

Short Course Audience:

The course is intended for engineers and technical managers who want an up-to-date overview of 400Gb/s transmission systems, including applications, line-card designs, and fiber transmission limitations. The course requires some understanding of basic optical transmission systems.

Instructor Biography:

Benny Mikkelsen is co-founder and CTO at Acacia Communications, where he is responsible for the design of 100Gb/s optical transport products. Before Acacia, he co-founded Mintera and earlier was with Bell Labs, Lucent Technologies, where his research included ultra high-speed optical transmission. He holds master's and doctorate degrees in electrical engineering from the Technical University of Denmark.

Martin Birk received his master's and doctorate degrees from Germany’s University of Ulm in 1994 and 1999, respectively. Since 1999, he has been with AT&T Labs in New Jersey, working on high-speed optical transmission at data rates of 40Gbit/s, 100Gb/s and above.
