Abstract :
We have fabricated and tested an optical transmitter module with a built-in modulator driver IC and a receiver module with a built-in preamplifier IC, both designed for use in 10 Gb/s optical communication systems. Newly developed circuits enabled high-speed transmitter modulation characteristics with short rise and fall times of 18 ps and 21 ps, respectively, and a low-power consumption of 1.1 W. High-sensitivity of -26.1 dBm and a wide-bandwidth of 9.2 GHz were obtained from the receiver. Using a transmitter and receiver pair, we obtained back-to-back sensitivity of -24.8 dBm, and power penalties of 0.8 dB over a 60 km single-mode-fiber (SMF) transmission and 1.7 dB over an 80 km SMF transmission. The sensitivity over the 80 km SMF transmission, and these power penalties, are the best yet reported.
