摘要： An object of the invention is to provide a wavelength division multiplexing optical transmission apparatus and a wavelength division multiplexing optical transmission method which are capable of reducing the transmission quality deterioration of polarization multiplexed optical signals generated in an optical fiber transmission line and are suitable for dense wavelength division multiplexing. A wavelength division multiplexing optical transmission apparatus (11) includes a plurality of polarization multiplexing optical modulation means (2-1 to 2-N), polarization-maintaining optical multiplexing means (3), and delay adjustment means (4). The polarization multiplexing optical modulation means (2-1 to 2-N) generate a plurality of polarization multiplexed optical modulation signals (P-1 to P-N) having different wavelengths. The polarization-maintaining optical multiplexing means (3) multiplexes the wavelengths of the polarization multiplexed optical modulation signals (P-1 to P-N) to generate a wavelength multiplexed optical signal (WDM). The delay adjustment means (4) adjusts a delay such that light intensities of polarization multiplexed optical modulation signals having adjacent wavelengths in the wavelength multiplexed optical signal (WDM) vary inversely with respect to each other.

摘要： A transmission device includes: a plurality of modulators (13-1 to 13-4) that respectively generate multicarrier signals from given data; a distributor (12) that distributes input data to the modulators; an optical circuit (14-1 to 14-4, 15) that multiplexes the multicarrier signals to generate a WDM optical signal; and a controller (16) that obtains allocation information from a receiver of the WDM optical signal and generates a distribution instruction to control the distributor and a bit allocation instruction to control the modulators according to the allocation information. The allocation information is calculated based on transmission characteristics of each subcarrier of the respective multicarrier signals and the allocation information indicates a number of bits of data allocated to each of the subcarriers. The distributor distributes the input data to the modulators according to the distribution instruction. The modulators respectively allocate data distributed from the distributor to the subcarriers according to the bit allocation instruction to generate the multicarrier signals.

摘要： A system and method including a parity bit encoder for encoding each n−3 bits of data to be transmitted with three parity check bits to produce blocks of n bits (n−3 information bits plus three parity bits associated with the n information bits). Each of the blocks of n bits are Gray mapped to three QAM symbols that are modulated onto an optical wavelength and transmitted to a receiver. A maximum a posteriori (MAP) decoder is used at the receiver to correct for cycle slip.

摘要： The present invention relates to a multicarrier-based optical transmit subsystem and a method for generating an optical signal. The multicarrier-based optical transmit subsystem includes: a comb-shaped light source apparatus, configured to generate and output polychromatic light; a mirroring group, including multiple microring modulators, where each of the multiple microring modulators includes an input end and a download end, the input end of each of the multiple mirroring modulators is connected to the comb-shaped light source apparatus, and the multiple mirroring modulators each are configured to filter and modulate the polychromatic light, to obtain optical signals with different frequencies, and output the optical signals by using respective download ends of the multiple microring modulators; and a public waveguide, connected to the download ends of the multiple mirroring modulators, and configured to multiplex the optical signals with different frequencies. Optical signals with different frequencies are obtained by filtering and modulating polychromatic light by using a mirroring group, and are output to a public waveguide by using respective download ends of microring modulators. In this way, the polychromatic light can be split, and a modulation signal is loaded to optical carriers obtained by means of filtering, to obtain the optical signals with different frequencies; in addition, by connecting the download ends of the microring modulators in the mirroring group to the public waveguide, the optical signals with different frequencies that are obtained by means of modulation are multiplexed in the public waveguide, so that an extra demultiplexer and wavelength division multiplexer do not need to be disposed in a multicarrier-based optical transmit subsystem, and a structure of the multicarrier-based optical transmit subsystem is simplified, thereby reducing a cost of the multicarrier-based optical transmit subsystem.
