Research on Network Traffic Transmission Characteristics of Substations Based on FRFT System

This paper focuses on the characteristics of cosine-Gaussian beams in a fractional Fourier transform system and conducts research through theoretical derivation and simulation. In the research on the ideal fractional Fourier transform system, the parameter settings of a standard focal length of 2.0 meters, a wavelength of 1.06 micrometers, and a beam waist radius of 1.0 millimeter are adopted. For the fractional Fourier transform system with spherical aberration, the spherical aberration coefficient c takes the values of ±0.001, ±0.002, and ±0.003, and the modulation parameter is 3. The purpose of studying its transmission characteristics is to provide theoretical references for the research on network traffic transmission characteristics of substations. The paper introduces the theoretical basis and research methods of fractional Fourier transform, elaborates on the concept, image and properties of cosine-Gaussian beams, deeply analyzes their transmission characteristics in different fractional Fourier transform systems, draws relevant conclusions and looks forward to the future research directions.
