摘要
An analog fiber-optic link transporting the wireless code-division multiple-access (CDMA) signals requires the minimum dynamic range of only about 30 dB, Motivated by this relaxed requirement, we have recently proposed a passive optical network for CDMA-based microcellular communication systems. In this paper, we reviewed the basic design rules and demonstrated various networks using double-star and ring architectures, We implemented these networks by using inexpensive light sources such as a Fabry-Perot laser (for downstream) and light-emitting diodes (for upstream). The results show that these networks could support more than eight remote base stations located within similar to 10 km from the central base station.
