The invention belongs to the technical field of short-distance optical interconnection, and particularly relates to a PAM-4 signal generation system based on polarization multiplexing of an optical transmitter. According to the system, firstly, an optical signal generated by a laser passes through a polarization beam splitter to obtain two paths of optical signals of which the polarization quantities are X and Y respectively; two paths of optical signals and an OOK signal are respectively added to two Mach-Zehnder modulators, the two paths of optical signals are combined through a polarization beam coupler in front of a receiving end, the combined signals are received and demodulated through a photodiode, and finally high-frequency components are filtered out through a low-pass filter to obtain PAM-4 signals. The system disclosed by the invention does not adopt a digital-to-analog converter, is simple in structure and low in cost, and the transmission rate of the generated signal can reach ...
