Abstract

This paper presents a Low-Consumption Code integrated with polarization-multiplexed SAC-OCDMA and AND subtraction detection to address the demand for energy-efficient, high-capacity optical networks. The proposed LCC, characterized by short code length and low cross-correlation derived from a diagonal matrix-based design, reduces interference, simplifies signal recovery, and lowers transmission power requirements. Analytical results show that the system supports up to 146 users, a 61% increase over conventional MD code systems, while maintaining a BER below 10−9. The use of AND-subtraction detection enhances system scalability. It provides a 10.6% increase in user capacity by improving interference suppression and detection accuracy compared to the existing ZCC-coded system. The system also exhibits strong sensitivity to receiver effective power. The receiver power increases from –15 dBm to –10 dBm, and the number of users that can connect simultaneously rises from 118 to 156. Using orthogonal polarization states to improve energy efficiency, polarization multiplexing boosts spectral efficiency and lowers transmission power. In general, these results show that the LCC-coded PM-SAC-OCDMA architecture is a scalable and power-efficient option for next-generation metropolitan optical networks. It has more capacity, uses less energy, and operates reliably.
