Abstract

The next generation optical transport networks will be affected by a limited bandwidth of information infrastructure, high energy consumption, as well as the heterogeneity of optical networks. To address these problems simultaneously, we propose an adaptive software-defined LDPC-coded multiband scheme that involves spatial-MIMO and all-optical-OFDM scheme, which provides both fine granularity and elastic approach of bandwidth utilization. The modulation is based on multidimensional signaling to improve the tolerance to fiber nonlinearities and imperfect compensation of channel impairments. The proposed scheme employs hybrid (electrical and optical) degrees of freedom. Optical degrees of freedom include spatial and polarization modes in few-mode fibers. The electrical degrees of freedom are based on 2M orthogonal prolate spheroidal wave functions, which are used as basis functions for 2M-dimensional signaling. The adaptive coding has been performed by partial reconfiguration of the corresponding parity-check matrix. The proposed scheme is suitable for the conveyance of the information over optical fibers supporting a multitude of spatial modes to enable transmission of 10+ Tb/s bit rates.
