Document Type and Number:
WIPO Patent Application WO/2020/015109
Kind Code:
A1
Abstract:
The present invention relates to a multi-modulation-format compatible high-speed laser signal generation system and method. The present invention can greatly improve modulation format compatibility of a laser communication system and saves system upgrading costs and resource costs. The multi-modulation-format compatible high-speed laser signal generation system mainly comprises 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, 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 output end of the IQ modulator; the bias point control unit is connected to the IQ modulator.
