System performance of CDMA fiber optic LANs with non-ideal component models

Conventional multiple access schemes do not exploit the high bandwidth of the optical fiber. Direct-sequence spread spectrum systems are a class of code division multiple-access (CDMA) systems that encode data using high bit-rate sequences to spread data over a much wider bandwidth than is normally required for transmission. The performance of CDMA systems is investigated for laser chirping effects, and single mode fiber dispersion, 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
