The invention provides an
optical fiber communication
system nonlinear compensation module based on a
photon chip, and belongs to the field of
optical fiber communication. Comprising a
photon chip, an FPGA module, an ADC / DAC and a
light source, and the
photon chip, the FPGA module, the ADC / DAC and the
light source are utilized to build a full-connection neural network used for calculating nonlinear disturbance signals in the
optical fiber communication
system and compensating optical signals at a receiving end so as to improve the
transmission performance of the optical
fiber communication
system. According to the invention, the cascaded Mach-Zehnder Interferometer (MZI) array and the FPGA
electronic control unit are utilized to construct a photon neural
network computing system together, so that neural network operation can be executed at high speed and low
power consumption. The non-linear damage compensation module is used for compensating non-linear damage SPM, IXPM and IFWM generated in the single-mode
fiber transmission process, and can be used as a non-linear damage compensation module of a
digital signal processing technology in an optical
fiber communication system so as to improve the
transmission performance of the optical fiber communication system.
