Design of Hybrid DWDM and SAC-OCDMA System Utilizing ZCC Code to Enhance User Volume

Abstract

Zero Cross-Correlation (ZCC) code stands out amongst the most helpful codes in Spectral Amplitude Coding-Optical Code Division Multiple Access (SAC-OCDMA) system because of its features like zero cross-correlation and high auto-correlation. However, for long-range communication, as the number of user’s increases, the performance of the system is degraded. In this paper, we made an effort to enhance the performance of SAC-OCDMA system using Dense Wavelength Division Multiplexing (DWDM). SAC-OCDMA is an inseparable part of the global optical communication systems. It provides high speed, high bit-rate, security and high bandwidth for advanced services in different networks. Therefore, the hybrid DWDM and SAC-OCDMA system makes it believable to create other codes like multi diagonal (MD) and random diagonal (RD). Our results show that the number of users increases ten times by using a combination of 20-channel DWDM and SAC-OCDMA ZCC code system at a bit-rate of 10 Gbps for 60 Kms.
