This paper presents the numerical analysis of 2Dimensional (2-D) FCC-MDW of the Optical Code Division Multiple Access (OCDMA) based on variations of transmission bit rate. This 2-D OCDMA code is a combination of 1-D Flexible Cross Correlation (FCC) and 1-D Modified Double Weight (MDW). The performance of 2-D FCC-MDW is evaluated at different bit rate; 622Mbps, 1Gbs and 2.5Gbps and can be demonstrated by the bit error rate. The results indicate that the 2-D FCC-MDW can accommodate a larger number of users even at the higher user bit rate. Moreover, a lower effective power is also can be achieved.
