摘　　要：A variable weight address code based on spectrum amplitude coding(SAC)is proposed for optical code division multiple access(OCDMA)networks to support different quality of service(Qo S)requirements of different services.The zero cross-correlation magic square variable weight optical orthogonal code(ZMS-VWOOC)proposed in this paper has great flexibility in terms of code weight and number of users.Zero cross-correlation can eliminate the influence of multiple access interference(MAI)and reduce the system complexity.Numerical results show that ZMS-VWOOC can provide better quality of service than similar codes.Numerical results for a ZMS-VWOOC OCDMA network designed for triple-play services operating at 0.622 Gbit/s,2 Gbit/s,2.5 Gbit/s and 3 Gbit/s are considered.
