| Abstract: | The scheme of FBGs-based OCDMA spectral-amplitude-coding(SAC) for OCDMA system with optical orthogonal code is discussed; The designing and the achievement process of SAC encoder/decoder with)1,1,1(),,(2+++=qqqwNlare firstly submitted; The performance of this system, the SIR and BER resulted from multi-access interference (MAI), are also analyzed in detail under the condition that the powers of code chips are not uniform; the applied foreground of this system is predicted. |
