Sunday, 19 March
13:30 - 17:30
Short Course Level: Intermediate
Sander L. Jansen¹, Dirk van den Borne²; ¹ADVA Optical Networking, USA ²Juniper Networks, Germany
Short Course Description:
In this short course we will explain and compare the various flavors of multicarrier modulation, including DMT, OFDM and DWDM superchannels. The short course is focused especially on understanding multicarrier modulation in the context of the most promising network applications, ranging from cost-effective data center interconnects (DCI) to capacity-approaching superchannels in core networks. Attendees will understand after this short course how multicarrier modulation can be used to build adaptive and scalable transport beyond what is possible with single carrier modulation formats.
The course will describe the principles of multicarrier modulation schemes, and in detail explains the signal processing algorithms that are required for generation and detection for each of the different flavors of multicarrier modulation. We describe the most relevant transmitter and receiver architectures to generate and detect multicarrier signals (both analog and digital), as well as how to compensate for the different signal impairments in the transmitter and along the transmission link.
The course includes a strong focus on the different applications of multicarrier modulation formats. In particular, the wide range of architectures and technologies proposed for short-reach and cost-effective data center interconnections is explored in detail. In addition, we show as well how multicarrier modulation can scale metro and long-haul transmission systems beyond the maximum data rate achievable with a single optical carrier.
The course should enable attendees to understand both theory and technical realization of DMT, OFDM and DWDM superchannels as well as their most relevant applications in different types of optical transmission networks.
Short Course Benefits:
This course should enable you to:
Describe modulation and detection concepts of different multicarrier modulation formats such as orthogonal frequency division multiplexing (OFDM) and discrete multi-tone (DMT).
List different flavors of multicarrier modulation and detail the advantages and disadvantages of each modulation method.
Understand the state-of-the-art research on high capacity transmission systems and explore the limits of technology of multicarrier modulation.
Understand the different OFDM design trade-offs, such as cyclic prefix, FFT-size, etc. with respect to for instance the dispersion tolerance and oversampling.
Understand why DMT is often preferred over OFDM modulation for cost-effective short distance applications.
Explain the multi-input, multi-output (MIMO) technique that is required to equalize a polarization division multiplexed (PDM) or a mode division multiplexed signal.
Understand the different multicarrier modulation formats in the context of short-reach DCI and how to leverage the trade-off between optical performance and system complexity / cost.
Illustrate the advantage of multicarrier modulation in next-generation 400G/1T transport networks.
Short Course Audience:
This course is intended for engineers, researchers and technical managers who would like to gain a better understanding of multicarrier modulation formats and their applications in optical transport networks. Apart from the theory and concepts behind multicarrier modulation, the implementation and system design will be discussed in detail, such that the participants can obtain a good level of understanding for the different design trade-offs. Participants should have a comprehensive knowledge in the field of fiber-optic transmission systems; no previous knowledge of multicarrier modulation systems is required.
