Abstract
As a solution to limited bandwidth and high energy consumption of information
infrastructure as well as heterogeneity of optical networks, a hybrid multidimensional
coded modulation scheme is proposed employing all available electrical and
optical degrees of freedom. Electrical basis functions are based on either
modified orthogonal polynomials or prolate spheroidal wave functions, while
optical ones on polarization and spatial mode states. The proposed scheme
is both multi-Tb/s and beyond 100 Tb/s enabling technology. Additionally,
the proposed scheme provides the adaptive, software-defined, and dynamic allocation
of bandwidth with fine granularity. The adaptive coding is based on irregular
nonbinary quasi-cyclic LDPC codes, providing record net coding gains.
