In this paper, we compare the performance of two newly proposed MAC protocols for multirate optical CDMA (OCDMA) networks. The first protocol is the S-ALOHA/OFFH-CDMA and the second is the R3T/OFFH-CDMA. The main subject in this proposal is to exploit the potential of the optical fast frequency hopping CDMA using fiber-Bragg grating when jointly used with two different MAC protocols in a link layer as an effective way of integrating multirate traffic. The system throughput and the average packet delay are compared for both systems. It is shown that the S-ALOHA is better than the R3T when the user's activity and the offered load are high while the R3T is better for smaller values. Both protocols can be competitive in terms of the system throughput with the advantage is for the R3T protocol at moderate offered load. However, the R3T protocol suffers a higher delay mainly because of the presence of additional modes.
