DP-IQ Modulator Bias Controller
SUMMARY
"A DP-IQ modulator consists of two IQ modulators
and a polarization rotator. Each IQ modulator consists of three different modulators: I, Q arms are intensity modulators, P arm is a phase modulator. The DP-IQ modulator is typically applied to DPQPSK systems. Plugtech Precision Systems’ modulator bias controller is specially designed for DPIQ modulators to ensure stable operations in various operating environments. Based on its fully digitized signal processing method, the controller can provide ultra stable performance."
