Abstract
A WDM fiber radio system with improved spectral efficiency, incorporating remote LO delivery and FBG optical filtering techniques, is demonstrated. The network utilizes remote LO delivery together with multi-sector SCM signal transmission, using very narrowband optical filtering techniques via custom designed FBGs. Two different types of FBG designs are implemented and their performance is compared in an experimental system application. The results show that all channels within a 25 GHz band are successfully recovered with minimal degradation.
