Transmitter for a fiber optics multicarrier modulation transmission system using multiple polarizations

摘要

The transmitter is configured for a fiber optics multicarrier modulation transmission system, e.g., for an optical OFDM system. The transmitter is further configured to generate an optical multicarrier modulation signal comprising a plurality of different subcarriers, at least some of which being modulated. Each subcarrier in a first group of the subcarriers has a first polarization and each subcarrier in a second group of the subcarriers has a second polarization different from the first polarization.
