Seyedzadeh, Saleh and Mahdiraji, Ghafour Amouzad and Sahbudin, Ratna Kalos Zakiah and Abas, Ahmad Fauzi and Ahmad Anas, Siti Barirah (2014) Experimental demonstration of variable weight SAC-OCDMA system for QoS differentiation. Optical Fiber Technology, 20 (5). pp. 495-500. ISSN 1068-5200; ESSN: 1095-9912


In this paper the experimental and simulation results of variable-weight spectral amplitude coding optical code division multiple access (VW-SAC-OCDMA) system is demonstrated. In the proposed system, three users with weights of 6, 4 and 2 each operating at data rate of 1.25 Gb/s represent video, data and voice services, respectively. Results show that for back-to-back system minimum average power of −20 dBm per chip is required to maintain the acceptable performance. Transmission up to 60 km of fiber is demonstrated. Using mathematical approximation the capacity of VW-SAC-OCDMA system is demonstrated.
