Abstract: A transmitting device configured to obtain a message to be transmitted; map the obtained message onto a two-dimensional 2n-symbol constellation to obtain a sequence of discrete constellation symbols, where n is an odd number not less than 3. A receiving device configured to receive a sequence of noisy discrete constellation symbols; demap the sequence of noisy discrete constellation symbols to output data using a two-dimensional 2n-symbol constellation, where n is an odd number not less than 3.

Abstract: The invention presents an equalizing device, a corresponding method and an optical signal with a frame structure for enabling the method. The equalizing device includes a first 2×2 MIMO equalizer configured to perform a first equalization on the digital signal, supported by a 2×2 MIMO channel estimation of the channel based on the digital signal. Further, the device includes a second 2×2 MIMO equalizer, arranged after the first equalizer and configured to perform a second equalization on the digital signal, supported by a State of Polarization (SOP) estimation of the optical signal based on the digital signal.

Abstract: The disclosure relates to an optical device for wavelength division multiplexing of two or more input beams. The disclosure proposes the optical device, and a corresponding method for operating the optical device. The optical device comprises a multiplexer and two or more channels for the two or more input beams, wherein each channel is configured to receive one input beam of the two or more input beams and to provide a rotated beam, which has a polarization rotated compared to a polarization of the corresponding input beam, to the multiplexer, and wherein at least one channel of the two or more channels is configured to rotate the polarization of the corresponding input beam in a different direction than at least one other channel of the two or more channels.
