| Summary: | 碩士 === 國立高雄應用科技大學 === 電子工程系 === 105 === In this thesis, 100Gb/s coarse wavelength division multiplexing (CWDM) optical transmitter and receiver were developed for single-mode fiber (SMF) transmissions. For this transmitter, the distributed feedback (DFB) laser diodes (LDs) at 1270nm, 1290nm, 1310nm, and 1330nm were used in the TO-56 coaxial packaged transmitter optical subassembly (TOSA) modules. The TOSA modules can be controlled through four LD driver integrated circuits (ICs) with clock and data recovery (CDR), and the four optical signals were combined into a SMF through an optical multiplexer. For this receiver, the p-i-n photodiodes and transimpedance amplifiers were used in the TO-46 coaxial packaged receiver optical subassembly (ROSA) modules. The four-wavelength optical signal from the SMF was separated as four optical signals through an optical demultiplexer, and the ROSA modules can be controlled through four receiver ICs with CDR.
The 100-Gb/s CWDM optical transmitter and receiver had been realized and tested at four-channel 25.78Gb/s operation. In the transmitter, the extinction ratio, rise time, fall time, peak-to-peak jitter, and mask margin of the eye diagram for the best performance channel are 4.4dB, 14.47ps, 23.5ps, 15.7ps and 14.7%, respectively. In the receiver, the rise time, fall time, and peak-to-peak jitter of the eye diagram for the best performance channel after 10km SMF transmission are 16.9ps, 16.3ps, and 11ps, respectively. At 1270nm, 1290nm, 1310nm, and 1330nm, the dispersion power penalties after 10km SMF transmission are about 1.3dB, -0.5dB, 0dB, -0.5dB, respectively. Our CWDM optical transmitter and receiver had been verified and can be applied in 100Gb/s 10km SMF transmissions.
