Video Pulse Width Modulation for Optical Fiber Transmission

[摘要] This thesis describes theoretically the feasibility of two pulse width modulation (PWM) systems for transmission through an optical fiber. The first part of this work is devoted to the electronics of the two PWM systems. A comparison of the performance of each system is carried out. This comparison takes into account spectra, harmonic distortion, bandwidth requirement, system complexity and output signal to noise ratio (SNR). A comparison of PWM SNR and PCM SNR in the presence of intersymbol interference (ISI) is made. The second part is devoted to the optical system. The choice of optoelectronic devices, link losses, power budget, signal to noise ratio, and rise time budget are discussed.
