Characterization of multi-functional optical interface for multi-channel fiber-radio transmission in heterogeneous access networks

Abstract

Millimeter-wave (mm-wave) fixed wireless access with optical transport is able to provide future ultra-broadband connectivity. Optical single sideband with carrier $({\rm OSSB}+{\rm C})$ modulation has been shown to overcome dispersion for signal transport in such systems [1] while the optical spectral usage of ${\rm OSSB}+{\rm C}$ signals can be improved by interleaving the mm-wave modulated optical signals [2], [3]. The merging of fiber-radio applications with other access networks has also been demonstrated, leading to a transparent heterogeneous access architecture [4]. In a multiple radio environment the performance of the fiber-radio system is severely limited by the no..
