NEW! SC341 OFDM for Optical Communications

Sunday, March 21, 2010
9:00 a.m.–12:00 p.m.
Sander L. Jansen; Nokia Siemens Networks GmbH & Co. KG, Germany
Level: Beginner (no background or minimal training is necessary to understand course material)


Course Description

The course is divided into two parts: The first part will discuss the concept of OFDM and the design trade-offs that are relevant for fiber-optic transmission systems. Several methods for generation and detection will be discussed as well as MIMO processing. The second part of the short course will cover implementation aspects of optical OFDM. How can we generate and detect optical OFDM in the lab? How must we compensate for imperfections of, for instance, the optical modulator and the 90 degrees hybrid? The course should enable attendees to get a feel for the different concepts and implementations of optical OFDM and their application scenarios.


Benefits and Learning Objectives

This course should enable you to:

  • Describe the concept of orthogonal frequency division multiplexing (OFDM) and its implementation.
  • List the different kinds of optical OFDM that exist and detail the advantages and disadvantages of each method.
  • Discuss concepts and components for the generation and detection of optical OFDM.
  • Appreciate the design trade-offs of the cyclic prefix, FFT-size, etc. with respect to for instance the dispersion tolerance and oversampling.
  • Explain the multi-input, multi-output (MIMO) technique that is required to equalize a polarization division multiplexed (PDM) signal.
  • Describe concepts such as IQ imbalance mitigation and phase noise compensation.
  • Discuss different applications for optical OFDM, from access to long-haul transmission.

Intended Audience

This course is intended for engineers, researchers and technical managers who would like to gain a better understanding of optical OFDM and its applications. Apart from the theory and concepts behind optical OFDM, the implementation and system design will be discussed in detail as well. Participants should have a basic knowledge in the field of fiber-optic transmission systems.


Biography

Sander Lars Jansen is one of the pioneers in the field of optical OFDM for fiber-optic transmission systems. In 2007 he introduced a novel method for phase noise compensation and showed the first long-haul OFDM transmission experiment (4000km). Subsequently, in 2008 he was the first to realize 100-Gb/s per WDM channel. He authored and co-authored 10+ patents and more than 80 refereed papers and conference contributions. Dr. Jansen is an associate editor for PTL and an OFC committee member.
