40G速率 DQPSK/IQ鈮酸鋰調制器, 住友Sumitomo T.SBZH1.5-20PD-ADC, 雙驅型
住友Sumitomo T.SBZH1.5-20PD-ADC， 除了支持傳統的IQ/QAM調制類型，
雙驅型IQ調制器具有更大自由度來實現對子馬赫澤德干涉儀的每個臂進行任意相位控制，
以達到精確的相位匹配或者相位差，由此可以激發(fā)出更多新奇的應用，諸如光域中的混頻
或拍頻等ROF的應用，或者實現極高消光比，或飛秒超短的光脈沖輸出等等。
40Gbps DQPSK Modulator, Sumitomo T.SBZH1.5-20PD-ADC, Dual Drive IQ Modulator
This optical modulator is a DQPSK Dual-Drive( Quad GPPO) Mach-Zehnder modulator with
modulation speed of up to 22.5Gbaud.
The structure of dual drive MZ interferometers enables exact phase match or arbitrary phase
difference control, which make it ideal for some novel application.
This optical modulator integrates a monitor PD chip and coupler function for automatic bias
control (ABC) for the compensation system of DC-drift and other phenomena.
