Objectives
To give the student the generic concepts of fibre optic transmission systems discussing the principles of optoelectronics and fibre optics operation, with a practical perspective through the realization of laboratory projects.
Program
Introduction to optical fibre systems. Optical fibre, structures and propagation. Transmission characteristics: attenuation and dispersion. Optical fibre materials and fabrication techniques. LEDs and semiconductor lasers. Power coupling into optical fibres. Optical transmitters. Optical detectors PIN and APD. Optical receivers: digital and analogue, high-impedance and transimpedance. Design of point-to-point transmission systems. Wavelength division multiplexing optical systems.
