Abstract


Zero Cross-Correlation (ZCC) code is a standout 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 another is high auto-correlation. But, as the number of users increases, the performance gets degraded for long-range communication. So in this paper, an effort has been put to enhance the degraded system using Dense Wavelength Division Multiplexing (DWDM). Method: SAC-OCDMA is an inseparable part of the global optical communication systems. It consists of various consumers’ demands like capability for high speed, high bit-rate, security and high bandwidth for advanced services in local area networks and metropolitan area networks. The combination of SAC-OCDMA system with DWDM makes it conceivable to create other codes like Multi-Diagonal (MD) and Random-Diagonal (RD). The simulative analysis is performed using Optisystem11.0. Findings: 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 10Gbps for 60 Kms.
