碩士 === 國立高雄應用科技大學 === 電子工程系碩士班 === 103 === With the advancement of information and communication technology, people increase demanding speed to get the message, therefore, the demand of high-speed short-range transceiver devices also increase in data exchange centers. A 100GBASE-SR10 optical transceiver module consists of 12 channels of each 10-Gb/s transceiver to achieve 100-Gb/s operation. The 100GBASE-SR4 is defined in IEEE 802.3bm standards, and uses four channels to achieve 100-Gb/s operation. We designed a transceiver module based on the IEEE 802.3bm specification. In our module, the transmitter uses a quad 28-Gb/s laser driver integrated circuit (IC) and an 850nm wavelength quad 25-Gb/s vertical cavity surface emitting laser (VCSEL) array. The receiver uses a quad 28-Gb/s receiver IC and an 850nm wavelength quad 25-Gb/s photodiode array. Two quad 28-Gb/s clock and data recovery (CDR) ICs are also used in the transceiver to improve the performance of input and output signals. At last, the 100Gb/s SR4 multimode fiber optical transceiver. For transmitter measurement, the peak-peak jitter, rising time and falling time, were 14.092ps, 21.19ps and 20.45ps, respectively. For receiver measurement, the peak-peak jitter, rising time and falling time were 13.63ps, 20.27ps and 20.45ps, respectively. In the condition of bit error rate (BER) of 10-12, the sensitivity of receiver was 1.74dBm. In conclusion, it could enable the 100Gb/s SR4 multimode fiber optical transceiver to operate at 100Gb/s which has been proved from this result of measurement.
