Space-Division Multiplexed Transmission over 4200~km 3-Core Microstructured Fiber

We experimentally demonstrate space-division multiplexed transmission of 6 polarization- and space channels in a 3-core microstructured fiber over a distance of 4200 km. The spatial multiplexed channels consist of 5 wavelength multiplexed 40 Gbit/s QPSK signals with a 50 GHz channel spacing, resulting in a aggregate capacity of 1.2 Tbit/s over 250 GHz bandwidth. The signals are recovered using off-line coherent multiple-input-multiple-output digital signal processing.
