Recent Developments on Optical Single Sideband Transmission Systems

Abstract

Optical single sideband (OSSB) modulation has been recently proposed to increase the spectral efficiency of next generation transmission systems. Contrary to other spectrally efficient optical modulations, simple electrical compensation techniques can be used together with OSSB to mitigate the impairment of fibre dispersion. In this paper, we present recent results on the use of electrical dispersion compensation (EDC) with OSSB modulation and assess ways to improve the EDC efficiency by using formats other than the conventional binary format
