Multifunctional optical interface for fiber-radio systems in heterogeneous access networks

Abstract

In this paper, we investigate through simulation a proposed multi-functional optical interface incorporating an arrayed waveguide grating (AWG) that multiplexes multiple wavelength-interleaved dense-wavelength-division-multiplexed (DWDM) optical RF channels while simultaneously reducing intermodulation distortion (IMD) in fiber-radio systems incorporating optical single sideband with carrier (OSSB+C) modulation. The proposed optical interface is also able to simultaneously support multiple baseband transmission in an integrated wireless/wired heterogeneous access environment. We derive an analytical model and present a detailed analysis of the proposed interface to establish the viability of..
