Quality of service in OCDMA

Abstract

Quality of Service (QoS) is the standard of technology. This paper analyzes various parameters of Optical fibre CDMA (OCDMA) technology that satisfies need of subscribers. QoS is provided by OCDMA when criteria of high data rates, high capacity, security and maximum subscribers are satisfied. Specifically High data rate codes (signature sequence) like optical orthogonal code (OOC’s) with mathematical analysis, capacity, bit error rate (BER) with mathematical analysis and reduction in multiple access interference (MAI) of OCDMA and security systems for maximum users are discussed. Reduction in MAI is using optical hard limiter in front of desired optical correlator is presented. Security enhancement by code switching is presented. Overall our analysis shows that OCDMA is well suited for maximum users considering QoS management.
