In this manuscript, we have analyzed a Spectral Amplitude Coding-Optical Code Division Multiple Access (SAC-OCDMA) System. The uniform Fiber Bragg Gratings (FBGs) are used at transmitter and receiver end to improve the overall performance of the system. Multiple Access Interference (MAI) has been reduced using a mathematical model and MDW codes for the proposed system. Further, we have transmitted data at 100 Gbps rate up to a distance of 80 Km by increasing the ten numbers of FBGs. The proposed system has been analyzed in terms of output power, distance, BER and Quality Factor. The Optisystem7 tool has been used to analyze the system performance.
