Summary: | 碩士 === 國立交通大學 === 光電工程研究所 === 104 === In this work, we propose the following specific points: Firstly, OFDM signal cause nonlinear effects in the E/O conversion; Secondly, we develop Predistortion and Post-filter technique to compensate the nonlinear effects, and correct the waveform in DSP offline. Furthermore, we apply NLC technique in different device including 980nm single mode VCSEL and 850 multi-mode VCSEL. Last but not the least; we demonstrate the transmission performance of the 980nm single mode VCSEL. We successfully demonstrated an optical OFDM transmission with employing a 980-nm VCSEL. With applying bit-loading algorithm and NLC technique, we successively achieve a 53.51 GHz 100-m, 50 GHz 200-m, 47.55 GHz 300-m and 42.38 GHz 500-m OM4 fiber transmission.
