Book excerpt: [ANGLÈS] After the extremely fast growth over last two decades, single-mode fibers capacity is reaching its recently revealed fundamental limit, imposed by a combination of Shannon's information theory and fiber nonlinearities. Such fact, together with the continuous growth of traffic demand, requires an urgent solution to overcome a capacity crunch. Space-division multiplexing (SDM) is a promising new paradox that makes use of the space dimension to increase capacity of optical links. Along this work, we will study different SDM approaches based on few-mode fibers (FMF) and multi-core microstructured fibers (MC-MSF) working under a high crosstalk regime. We will show that under this regime, the use of multiple-input multiple-output (MIMO) digital signal processing (DSP) is required to undo coupling or remove crosstalk between transmitted signals. Two experiments will be shown to reveal the power of space-division multiplexing. In the first experiment, we will demonstrate a transmission of six 40 Gb/s QPSK signals over 1200 km of FMF. While in the second experiment, we will present a WDM-SDM transmission through 4200 km of MC-MSF, leading to an aggregate bit rate of 1.2 Tb/s over a 250 GHz bandwidth. The record distances achieved with such high spectral efficiencies indicate that SDM systems based on FMF and MC-MSF, combined with MIMO-DSP, are promising candidates for future high capacity long-haul optical transmission systems.
