Signature sequences in OCDMA play a crucial role to judge the performance of system. In this paper, the authors present the analysis of newly designed model for 3D OCDMA system based on spreading in temporal, spectral and spatial domain using optical orthogonal codes and cubic congruent operator from Galois field GF (5) for four users at variable data rate. Codes thus designed supports transmission till 5 Gbps with acceptable level of received power level and BER. Results are shown in terms of eye diagrams, signal strength and BER by considering parameters such as variable data rate, received power and code dimensions. In comparison to other OCDMA system, designed system behaves exceptionally well at the considered parameters.
