This paper has been focused to utilize the m-sequence code in spectral/time/spatial OCDMA domain in a bipolar mode (Three Dimensional modes). The scheme has elegantly incorporated the design of an encoder and a decoder such that the system efficiently generates the code in three-dimensional bipolar mode. The decoder design is such that it effectively suppresses the multiple user interference (MUI) of three-dimensional code. System analyses are carried for defining the BER performance variation with users acceptability and received power. The observed results demonstrate that the cardinality of m-sequence three-dimensioanl bipolar code is larger than the existing 3D Pascal code, 2D -MDW,3D -PDC, 2D-PDC, 1D-CWH and 1D-MS codes. The received power in proposed system is -5.8dBm is lesser than the 3D Pascal Code at 10 -18 similarly the users adoption in system more than 210% can be accomplished as compared to 3D Pascal code.
