A new code structure for Spectral Amplitude Coding (SAC) in Optical Code Division Multiple Access (OCDMA) is developed and presented. This new code is called Multi Weight (MW) code. Beside the ease of implementation, this code has the advantage due to the flexibility of choosing any number of users and any weight with minimum code length. Results also indicate that this code perform well from other codes in its class in term of cardinality and system performance. The performance of this code in the existence of noise is also evaluated using Optisys version 7.0. It has been shown that the performance of OCDMA system can be improved by utilizing the new code compared to other codes in the SAC code family.
