Requirement of Modulation Bandwidth for 100Gb/s Optical DQPSK Transmission Using One Dual-drive Mach Zehnder Modulator

摘要：

This paper demonstrates bandwidth requirement for optical DPQSK transmitter using one Dual-drive Mach Zehnder Modulator (DDMZM) for 100Gb/s physical transmission. The result shows that at receiver bandwidth of 40GHz, NRZDQPSK signal requires 60GHz modulation bandwidth at least, while RZ-DQPSK scheme demands less bandwidth, about 40GHz for 50％ duty cycle RZ-DQPSK signal.
