We propose the new family of newly constructed codes named the one-dimensional Multi method codes (1-D MM codes) in the spectral amplitude coding optical code division multiple access (SAC-OCDMA) system. The new 1-D MM codes have the auto-cross correlation constraint and cross correlation constraint to be p and zero, respectively. Furthermore, the 1-D MM codes use the easy proposed structure. The proposed structure can use each transmitter, optical connected ring set (OCRS), and each receiver to become the one optical ring network. The proposed system uses the control path to give the user controller, correct optical fiber controller and failure optical fiber controller to achieve the one optical ring network. The numerical results demonstrate that the bit error rate (BER) in the proposed system using the 1-D MM codes outperform that in other systems using the 1-D M Sequence codes, 1-MQC codes, and 1-D RSQC codes. Then, the data transmission rate of the 1-D MM codes can achieve the 2.5 Gbps.
