碩士 === 國立交通大學 === 光電系統研究所 === 104 === Because of the vigorous development of interactive electronic products over the past decade and transmission technology in the old era of information transmission capacity is obviously insufficient. In the context of the need for more and faster transmission of information to improve the quality and quantity of the various transmission capacity. The short-haul communication transmission network design must take into account the spectrum efficiency (SE) and the spectrum transmission unit volume, and therefore the digital signal processing based on an Orthogonal Frequency Division Multiplexing technology (OFDM) become one of the selection in the future network. Therefore, this paper proposes a novel technology without a gap direct detection type polarization orthogonal frequency division multiplexing (DD-PDM-OFDM) demodulation, signal quality under close without gaps still remain fairly level and success will signal demodulation, and application to a multi-polarization, in the case of simulation of success in any polarization state (state of polarization, SOP) under the transmission and demodulates success, and successfully validated experimentally in the absence of any bit error rate is less than one-thousandth under the circumstances the smooth transmission of 100 km optical fiber, and successfully maintain signal quality and transmission capacity of 40Gbps, and not because of the dispersion caused by the decrease in the effectiveness of any system.
