【 摘 要 】

Future Internet technologies will be affected by limited bandwidth of information infrastructure, high energy consumption, and heterogeneity of optical networks. In order to simultaneously solve these problems, we propose an adaptive multidimensional mode-multiplexed software-defined LDPC-coded modulation scheme suitable for few-mode-fiber-optic communications enabling beyond 10-Tb/s optical transport. This scheme employs the optimum multidimensional signal constellations and generalized OFDM operation principle. The proposed scheme significantly outperforms the corresponding scheme based on conventional polarization-division multiplexed QAM.
