Capacity analysis for WDM fiber-radio backbones with star-tree and ring architecture incorporating wavelength interleaving

We present a model based on link budget calculations to investigate the capacity of a wavelengthdivision-multiplexed (WDM) fiber-radio backbone incorporating a wavelength-interleaving technique. The wavelength-interleaving technique improves the optical spectral efficiency of the millimeterwave fiber-radio systems incorporating optical single sideband with carrier modulation. In this paper, we investigate the capacity limitations of WDM fiber-radio backbones incorporating both wavelength interleaving and optical single sideband with carrier modulation for star-tree and ring architecture. The analysis provides an estimation of the overall system capacity and an insight into the network layout and performance limitations.
