Extended Single-Sideband Light Intensity Modulation Formats

Abstract

A theoretical analysis of various single-sideband modulation formats used in fiber-optic communication lines with an external electrooptical two-electrode Mach-Zehnder modulator for generating optical signals resistant to dispersive power degradation has been performed. A family of new single-sideband modulation formats is presented, the features of their use, advantages, and disadvantages are considered. A decrease in nonlinear distortions of signals during their transportation through dispersive optical fiber is assumed.
