Multi-modulation-format compatible high-speed laser signal generation system and method
The disclosure relates to a multi-modulation-format compatible high-speed laser signal generation system and method. The disclosure can greatly improve modulation format compatibility of a laser communication system and saves system upgrading costs and resource costs. The system mainly includes a control instruction unit, a serial-parallel changeover switch unit, a precoding switch unit, a power control unit, an IQ modulator, a narrow line width laser, and a bias point control unit, wherein the control instruction unit is respectively connected to the serial-parallel changeover switch unit, the precoding switch unit, the power control unit, and the bias point control unit; the serial-parallel changeover switch unit, the precoding switch unit, the power control unit, and the IQ modulator are electrically connected in sequence; the narrow line width laser is connected to an optical input end of the IQ modulator; and the bias point control unit is connected to the IQ modulator.
