A novel 2D polarization-spatial encoding approach for OCDMA system based on multi-core fiber

OCDMA plays an important role in optical fiber communication, this technique provides multiple attractive features such as the choices of exploiting several encoding approaches (Time, wavelength, ……). In this paper, we propose a novel encoding approach using the multi-cores fiber to generate the code words, this technique helps to avoid the complexity of encoding and decoding methods, limits the nonlinearity effects by sharing the signal power between cores, and promotes MCFs to enhance the system security. The proposed solution exploits ZCC code to check the efficiency of this method due of its properties such as the null cross correlation. Herein, the polarization provides a solution for compounding bitrate and the number of users. Also this approach moves OCDMA from the access network, to be adopted for long haul distance and high data rate.
