In addition to supporting the traditional IQ/QAM modulation type,the dual drive IQ modulator has a greater degree of freedom to achieve arbitrary phase control for each arm of the sub Maher Zed interferometer to achieve accurate phase matching or phase difference.

40G IQ/QAM 鈮酸鋰調(diào)制器 Modulator Sumitomo 住友 T.SBZH1.5-20PD-ADC Dual Drive Modulator
Description
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.

Features
  • Dual-Drive for each Child MZ Interferometer, which enables RF Phase Fine Tuning
  • Low Drive Voltage, RF VπVoltage 4.0V@20Gps, Typ
  • Separated DC Bias Port, Integrated Monitor Photodiode for Auto Bias Control
  • Low Insertion Loss, ≤9dB Typ
  • Polarization Maintaining Fiber at Both Input and Output

Application
  • 40Gps DWDM DQPSK Optical Transmission System
  • Measurement Equipment for High Speed Telecommunications
  • 4QAM, 16QAM, 64QAM Modulation
  • Radio over Fiber Applications, Ultra High ER Optical Pulse GeneratT.SBZH1.5-20PD-ADC-overviewion
