In this paper we design a central controller in the optical CDMA network which assigns multimedia code set to users. Because different kinds of services can tolerate different degree of reliability, we can assign codes to users according to its request service type. For example, users who transmit data service must guarantee the transmission efficient, thus we assign high reliable codes to users. On the contrary, voice and video services can tolerate some errors in its transmission process, thus we assign a low reliable codes to these kinds of services. In this paper, we use genetic algorithm (GA) to select the code set which contains different degree of reliable codes. By this solution, we can easily select the code set and assign to users according to the user's request
