Capacity analysis for WDM fiber-radio backbones with star-tree and ring architecture incorporating wavelength interleaving
ABSTRACT We present a model based on link budget calculations to investigate the capacity of a wavelength-division-multiplexed (WDM) fiber-radio backbone incorporating a wavelength-interleaving technique. The wavelength-interleaving technique improves the optical spectral efficiency of the millimeter-wave 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.
Conference Proceeding: Multi-carrier and m-QAM modulation based on integrated single side band lightwave source[show abstract] [hide abstract]
ABSTRACT: System experiments of a fully integrated millimetric single-side-band lightwave source are reported. Complex modulation schemes (64 QAM) are transmitted on 38-GHz carrier with very clear constellation and good bit error rate. Four-carrier transmission is also demonstrated with low penaltyOptical Fiber Communication Conference, 1999, and the International Conference on Integrated Optics and Optical Fiber Communication.
