SC341 - Multi-carrier Modulation: DMT, OFDM and Superchannels

Monday, 12 March
13:30 - 17:30

Short Course Level: Beginner


Sander L. Jansen¹, Dirk van den Borne²; ¹ADVA Optical Networking, Germany, ²Juniper Networks, Germany

Short Course Description:

In this short course, we will explain and compare the various flavors of multicarrier modulation, including OFDM, DMT, subcarrier multiplexing and DWDM superchannels. The short course is focused especially on understanding multicarrier modulation, and how this can be applied in the context of the most promising network applications. We show how this technology can scale from cost-effective short-reach and metro applications to capacity-approaching superchannels in long-haul transmission systems and beyond the maximum data rate achievable with a single optical carrier.

The short course describes the theory of multicarrier modulation schemes, 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. We especially explore in detail the different signal processing algorithms that are required for the generation and detection for each of the different flavors of multicarrier modulation.

The short course should enable attendees to understand both the theory and practical realization of DMT, OFDM, subcarrier multiplexing and DWDM superchannels as well as their most relevant applications in different types of optical transmission networks. The goal is for attendees to understand after this short course how multicarrier modulation can be used to design adaptive and scalable optical interfaces beyond what is possible with single carrier modulation formats.

Short Course Benefits:

This course should enable you to:

  • List different flavors of multicarrier modulation and detail the advantages and disadvantages of each modulation method.

  • Describe modulation and detection concepts of different multicarrier modulation formats such as orthogonal frequency division multiplexing (OFDM), discrete multi-tone (DMT) and sub-carrier multiplexing.

  • Understand the different OFDM design trade-offs, such as cyclic prefix, FFT-size, etc. with respect to for instance the chromatic dispersion tolerance and oversampling.

  • Explain the multi-input, multi-output (MIMO) technique that is required to equalize a polarization division multiplexed (PDM) signal.

  • Understand the state-of-the-art research on high capacity transmission systems and explore the limits of technology of multicarrier modulation.

  • Understand why DMT is often preferred over OFDM modulation for cost-effective short distance applications.

  • Understand the different multicarrier modulation formats in the context of cost-effective short-reach systems and how to leverage the trade-off between optical performance and system complexity / cost.

  • Understand how multicarrier modulation formats can be used to optimize the nonlinear tolerance in long-haul transmission systems and therefore can provide a key advantage in next-generation 400G 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 practical 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 as well as optical modulation and detection; no previous knowledge of multicarrier modulation systems is required.
