Abstract :
We examine the effect of the optical fiber group velocity dispersion (GVD) on wavelength-hopping time-spreading (WHTS) optical code division multiple access (OCDMA) networks. We introduce a new and generic modeling methodology for multi access interference (MAI) and bit error rate (BER) estimation. This methodology is applicable to realistic networks with fully asynchronous operation and is valid for any type of code. The efficacy of our model is tested using two different codes; prime-hop and Bin´s one coincidence codes. Modeling results and studies of BER performance are reported and indicate the inappropriateness of standard single mode fibers for use in WHTS-OCDMA networks when contrasted to dispersion shifted fibers (DSFs).
