In 1-D optical orthogonal codes, the ratio of code length to the code weight grows rapidly as the number of users increase. If we consider two-dimensional optical orthogonal code then it reduces the length of the code as a result of which BER performance of the system improves. In this paper we have discussed the performance analysis of an incoherent optical code division multiple access scheme based on wavelength/time codes. The OCDMA system is designed for 36 users at 1 Gbps. It is observed that the system can support only 25 users for permissible BER of 10-9,with 15db received power. The performance of the system is also analyzed based on BER and eye diagram under the influence of number of simultaneous users with different received power.Keywords
