Description
The QPSK-DP/SP Modulator Bias Controller Box (MBC-QPSK) is a powerful bench-top device designed to control the bias positions of DP/SP QPSK modulators used in high-speed optical transmission applications like 80Gbit QPSK or QAM systems. This controller is engineered to manage multiple bias points, ensuring precise operation for differential quadrature phase-shift keying (DQPSK) modulators, which enhance optical transmission properties such as reach, dispersion tolerance, and spectral efficiency.
The controller can handle up to six modulators, adjusting the first and second modulators to Null or Peak modes and the third modulator to Quad mode. Users can remotely control the locking slope via USB, while the system supports three operation modes: DQPSK, QAM, and Arbitrary Waveform. Integrated photodiodes provide real-time feedback of the input power, and the bias voltages are fully adjustable through the computer interface.
With its compact design and versatile control options, this controller is an ideal solution for researchers and engineers working with complex optical modulator systems.
