Abstract
Spectral Amplitude Coding (SAC)-based high-speed optical code division multiple access (OCDMA) network with fiber Bragg grating (FBG)-based encoders and decoders is provided in this research. The system makes use of FBG filters to provide exact wavelength-selective encoding and decoding, which minimizes the impact of multiple access interference (MAI) and increases system scalability. Phase-induced intensity noise (PIIN) is reduced and bit error rate (BER) performance is enhanced with a modified and additional amplitude coding method. The FBG-SAC OCDMA system shown here has zero crosstalk, enhanced transmission quality, and multiuser capabilities, according to numerical simulation. Quantitative research is also done on the impact of important factors including channel spacing, FBG reflectivity, and code length. The findings validate the viability and effectiveness of the suggested architecture for high-capacity optical access networks of the future.
