SC384 - Background Concepts of Optical Communication Systems
Sunday, 19 March
09:00 - 13:00
Short Course Level: Beginner
Alan Willner; Univ. of Southern California, USA
Short Course Description:
Optical communication systems have provided ever-increasing data transmission capacities, and there is a set of core concepts that are fundamental to understanding many of the crucial technical areas. The OFC/NFOEC conference has numerous courses teaching advanced topics that require some basic prior knowledge of these core concepts. The intent of this short course is to provide key background information to enable attendees to subsequently take more advanced courses as well as to enhance the attendee’s understanding of technical sessions throughout the conference.
An attendee will obtain an overview of the field that concentrates on a number of specific topics, including:
1. Introduction to optical systems (point-to-point links, reconfigurable networks, line/client, switching techniques)
2. Communications concepts (SNR, ISI, BER, PRBS, eye diagrams, link budget, data standards)
3. Channel multiplexing techniques (time, wavelength, subcarrier, space, polarization)
4. Fiber-based data-degrading effects (loss, chromatic dispersion, polarization-mode dispersion, polarization-dependent loss)
5. Amplifiers (EDFA and Raman, gain flattening, gain transients)
6. Nonlinear effects, dispersion management and fiber types
7. Modulation formats, capacity and data constellations (OOK, PSK, DPSK, QAM, OFDM)
8. Direct and coherent detection schemes
9. Mitigating data impairments: optical (tunable compensators) and electronic (DSP, FEC)
10. Basics of lightwave system modeling
Short Course Benefits:
This course should enable you to:
Understand basic concepts of an optical communication system.
Identify different types of modulation and multiplexing formats.
Compute a simple optical power budget.
Explain key differences between direct and coherent detection systems.
Attend more advanced OFC short courses and understand better the conference technical sessions.
Short Course Audience:
This introductory course is intended for an audience with at least some technical background in engineering, physics or related disciplines, and is ideally suited for engineers who want to learn more about optical fiber communication systems. The audience should gain valuable knowledge enabling them to take more advanced courses as well as understand better the conference technical sessions.
