What it is about
You will learn the structure, components and physical principles of modern wavelength-division-multiplexed optical transmission systems. In the end you will be able to apply physical models of important components and transmission links, analyze systems, numerically simulate with Matlab, and optimize for given boundary conditions.
What you will be able to do
- Understand the structure of WDM transmission systems
- Knowledge of optical transmitters and modulators (LED, diode laser, MZM, I/Q, polarization)
- Understanding physical properties of single-mode fibers (attenuation, chromatic dispersion, PMD)
- Identify and assess fiber non-linearities (FWM, Raman, SPM, XPM)
- Knowledge of optical amplifiers (Semiconductor, Raman, EDFA) and filters
- Understand differences between direct detection and coherent detection
- Modeling of signal propagation with the nonlinear Schrödinger equation and numerical solution
- Performance evaluation of transmission systems (BER, system margin, system penalty)
- Apply electrical/optical equalization and optimized system design
- Conduct and interpret Matlab simulations for system analysis
