r are analyzed systematically by optimizing and testing the algorithm model of semicon-
ductor optical results show that the optimal conditions for amplitude modulation or phase modulation is
the bias current of 1 00 mA and input power of -5 dBm or -20 dBm, 20 km bidirectional transmis-
sion communication system with a communication rate of Gb /s is analyzed and built,the bidirectional and unidi-
rectional transmission of upstream and downstream for optical network unit integrated with semiconductor optical am-
plifier and distributed feedback laser is forward bit error rate is ×1 0 -4 ,the sensitivities reach
- dBm and -31 .4 dBm for bidirectional upstream and downstream,and the sensitivities reach - dBm and
- dBm for unidirectional upstream and downstream,respectively.
Keywords:optical communication;semiconductor optical amplifier;gain;noise figure;distributed feedback laser
