N2 - 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, NRZ-DQPSK signal requires 60GHz modulation bandwidth at least, while RZ-DQPSK scheme demands less bandwidth, about 40GHz for 50% duty cycle RZ-DQPSK signal.
