Many codes have been proposed for the Spectral

Amplitude Coding (SAC) Optical Code Division Multiple Access (OCDMA) systems that has variable weights of greater than two. The best cross correlation property of these codes can only achieve a minimum cross correlation of one. To satisfy this, this paper propose a new SAC-OCDMA code with ‘zero cross correlation’ property which is crucial in minimizing Multiple Access Interference (MAI) effect.
