| Abstract: | This paper investigates the performance of a given gigabit optical code division multiple access (O-CDMA) network for two distinct families of two-dimensional (2-D) codes. The purpose of this analysis is to provide additional information regarding code adequacy to a given system availability so that performance optimization can be more efficiently carried out. The analysis takes into account construction aspects of the codes as well as dispersive and nonlinear effects in the single-mode fiber (SMF), such as group velocity dispersion (GVD), polarization mode dispersion (PMD), self-phase modulation (SPM), and cross-phase modulation (XPM). The analysis focuses on four different transmission rates, i.e., 1.25, 2.5, 5, and 10 Gbit/s, and describes how signal degradations impact the performance of the network. The simulations are carried out for a back-to-back system and for a 50-km dispersion-compensated fiber-optic link. |
