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.
