Distribution of 3G Base Stations on Passive Optical Network Architecture

Combining gigabit passive optical network (GPON) architecture with radio over fibre (RoF) technology could be a cost-efficient and attractive solution for operators for the distribution of 3G base stations (BS). We have implemented a PON delivering 2 BS with WDM lasers at remote base station (RBS) and a single photodiode at the Central Office (CO). An experimental study of this architecture for two BS has been performed and successful transmission has been shown for both uplink and downlink transmission. These results have been used to demonstrate the feasibility of distributing 12 3G BS over a 20 km link on a GPON architecture
