HY-ABC-MZ Series Automatic Bias Point Controller
Classification:
HY-ABC-IQ Series Automatic Bias Point Controller An automatic bias point controller for lithium niobate IQ modulator. It can be used in QPSK, QAM, OFDM, SSB and other modulation format systems. The automatic bias point controller can be integrated with other circuits using the lithium niobate modulator, or it can be used as a separate module. When used as a separate control module, it only needs to provide power through its own power adapter.

Modulator type
IQ---IQ modulator
Operating wavelength:
15---1550nm
13---1310nm
Power board selection:
P01 --- with power board
P00-without power board
Control Options:
R01 --- with serial port adjustment

Principle block diagram:
1. Connect the 1% end of the coupler to the detector pigtail of the bias point controller;
2. Connect the bias output of the bias point controller to the bias pins of the modulator (I, Q and P);
3. Power up the bias point controller (± 15V DC), and the one with power board can be directly connected with the adapter.
4. Turn on the switch on the power board, and the bias version starts to work.
Note: Be sure to load the RF signal before allowing the bias point controller to operate.
