Abstract :
We present an analytical model for the determination of blocking probabilities in an OCDMA Passive Optical Network (PON) that accommodates multiple service-classes, under a code reservation policy. The analysis considers fixed-length and fixed-weight codewords, while the provision of multi-rate differentiation is realized through the application of the parallel mapping technique. The user activity and different sources of additive noise are incorporated in our study. The model accuracy is completely satisfactory and is verified through simulation.
