We revise the latest advances on ultra-high throughput transmission using crosstalk-limited single-mode multicore fibers and compare these with the theoretical spectral efficiency limits of such systems. We relate the crosstalk-imposed spectral efficiency limits with fiber parameters, such as cladding diameter, core pitch, and trench design. Furthermore, we investigate the potential of techniques such as direction interleaving and highorder MIMO to improve the throughput or reach of these
