Abstract
Spectral amplitude coding optical code division multiple access (SAC-OCDMA) is a promising innovation for burst and asynchronous environment. This paper endeavors to analyze the efficacy of the proposed optimum SAC-OCDMA system by utilizing enhanced double-weight (EDW) code for six users operating at a bit rate of 60 Gb/s (10×6 Gb/s). Also, an algorithm is designed for EDW code with mapping technique for any weight that can be greater than two. The EDW code is analyzed for bit error rate (BER) and Q-factor using direct detection technique. Further, the system is compared with three dispersion compensating techniques (pre, post and symmetrical). The results indicate that by using symmetrical compensation the maximum usable distance increases to more than twice as compared to without compensation for the targeted BER (10−9), whereas by using p- and post-compensation the BER value increases to 10−13 as compared to without compensation whose BER value is 10−5. The comparison results show acceptable performance improvement.
