A novel non-coherent OCDMA system using one-dimensional expanded Hybrid codes for fiber failure recover scheme

We propose leveraging one-dimensional expanded Hybrid codes (1-D E-Hybrid codes) for two-code keying (TCK) in spectral amplitude coding (SAC) optical code division multiple access (OCDMA) networks. The proposed system can utilize all codes and provide a larger code size. The numerical results demonstrate that the 1-D E-Hybrid codes for TCK outperform the existing 1-D approaches, and the data transmission rate can achieve 2.5 Gbps. Then, the proposed system provides the fiber failure recover scheme on the system architecture. The proposed system can maintain the transmission and efficiency with fiber failure recover scheme when the fiber failure is suddenly happen.
