 Optical fiber communication dominates the transmission of high-speed data traffic, owing to various physical, engineering, and economic factors. Worldwide efforts are continuously being made to research and develop optical communication technologies that can support both current and future Internet infrastructure. The expansion of optical networks necessitates a swift transition from scientific breakthroughs in research labs to telecommunications industry products and solutions. Furthermore, the ever-increasing demand for bandwidth and connectivity places constant pressure on the development of faster and more efficient optical fiber communications [@Winzer2017].
 
-Today, optical communication systems engineering is a multidisciplinary field encompassing various areas of science and technology, including laser science, photonic devices, fiber optics modeling and engineering, digital signal processing, and communications theory. As we approach the limits of information transmission through optical fibers, more sophisticated engineering is required for the construction of optical transmitters and receivers, involving advanced DSP [@Essiambre2010], [@Savory2010]. The emergence of high-speed application-specific integrated circuits (ASICs) and advanced DSP algorithms has propelled coherent optical transmission systems to the forefront of high-capacity transmission via optical fibers [@Sun2020].

 Whether in the research or development stages, the study of optical communication systems typically necessitates the use of robust computational models to simulate various aspects of the system. For instance, it may be essential to comprehend how information-carrying signals transmitted over fibers will be affected by propagation phenomena such as chromatic dispersion (CD), polarization mode dispersion (PMD), nonlinear effects, and noise [@Agrawal2002]. This information ultimately determines the performance metrics of the transmission system, which play a crucial role in selecting the most suitable technology to become an industrial standard.
