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 and 200Gb/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 and beyond optical systems in data center and service provider networks. It describes the requirements and expectations network operators will have on cost, power consumption, footprint, reliability, optical performance, and interoperability. We present practical design issues of 400Gb/s systems in long-haul, metro and data center networks, 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 different implementations and the achievable fiber transmission distance. We also look at future bit rates and technologies beyond 400Gb/s, including super-channel, flex-rate, and highly parallel short reach systems.
Short Course Benefits:
This course should enable you to:
Identify key requirements and drivers for 400Gb/s applications

Short Course Audience:
The course is intended for engineers and technical managers who want an up-to-date overview of 400Gb/s and beyond optical communications systems, including technologies, applications in different networks, and design trade-offs. The course requires some understanding of basic optical transmission systems.
