In recent years, with the rise of the emerging services such as 4K or 8K ultra-high-definition television, high-definition video games, cloud computing, etc., the users' demands for bandwidth have continued to increase. In order to solve this problem, the wavelength division multiplexing (WDM) based passive optical network (PON) is employed. However, when multiple wavelengths are transmitted simultaneously in the optical fiber, fiber nonlinearity issues would occur, reducing the system's capacity and transmission range. In this paper, different parametric effects on the fiber nonlinearity impairments, including four-wave mixing (FWM), cross-phase modulation (XPM), and stimulated Raman scattering (SRS), are adequately investigated by theoretical analysis and simulations. In addition, the fiber nonlinearity impairments induced sensitivity penalty and optical power changes in WDM-based PON are discussed in detail. Given that the constructed simulation systems incorporate modular design, advanced WDM techniques, and ensure compatibility and interoperability for upcoming network technologies and escalating bandwidth requirements, the results yielded offer in-depth insights into the nonlinear effects within WDM-based PON networks, along with comprehensive details for developing WDM-based PON networks of enhanced performance.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
