Abstract :
We employ photon-counting techniques to analyze the performance of an all-optical fiber-optic code division multiple access (CDMA) network incorporating multiple optical amplifiers. Our analysis is based on obtaining characteristic functions indicating the photon-count of the output of a block of CDMA code pulse to its input count. The bit error rate (BER) results are obtained using two methods, namely, saddle-point and Gaussian approximations. From our BER analysis, we develop some insight into the optimum distribution of optical amplifiers and their corresponding gain setting parameter
