Abstract

We investigate the performance of CDMA. systems with laser chirping effects, single mode fiber dispersion effect and by assuming a Poisson shot noise model for an APD receiver. We develop the time-domain simulation models for the functional blocks in CDMA LANs and evaluate the end-to-end system performance using these models. The use of direct sequence CDMA LANs attracts attention due to the improved usage of the bandwidth of the optical fiber [1] [2] . We investigate the effect of using non-ideal components (sources, medium, detectors) on the performance of such a CDMA fiber-optic LAN. In our simulation the system comprises of the following signal processing blocks—Data source (NRZ) , Electrically programmable encoder, Laser, Optical encoder and decoder, Single mode fiber and Receiver.
