A novel wavelength-time differential code division multiple access system is proposed for multirate transmission. The system model is given and analyzed. Differential detection can be adopted by assigning two orthogonal codes for one user and using these two codes to encode “1” and “0” with different period, respectively. When one-branch and zero-branch are balanced perfectly, the system can reduce the noise of background, thermal, dark current, and multiple access inference. Moreover, by varying the ratio of number of bit ”1” and bit “0” in data steaming, the multirate data stream transmission is achieved.
