<p>The present disclosure relates to a method, a transmitter, a receiver and a system for communicating information carried by a polarization divided optical signal in an optical fiber (220), which method comprises the actions of; producing and transmitting a polarization divided optical signal OTApol comprising optical sideband pairs SBLA, SBHA each having one sideband SBLA at a first polarization and an other sideband SBHA at a second polarization that is orthogonal to the first polarization, and where the one sideband and the other sideband carry the same set of information A; and receiving and detecting the polarization divided optical signal OTApol so as to produce an electrical signal RFApol corresponding to the polarization divided optical signal; and down converting the electrical signal so as to produce, for each sideband pair, a first converted signal BBLA corresponding to the one sideband SBLA and a second converted signal BBHA corresponding to the other sideband SBHA; and extracting the set of information A for each sideband pair using a polarization diversity scheme operating on the first converted signal and the second converted signal of each sideband pair.</p> |
