200 Gbit/s 16QAM WDM transmission over a fully integrated cladding pumped 7-core MCF system

A complete, realistic integrated system is investigated, consisting of directly spliced 7-core MCF, cladding-pumped 7-core amplifiers, isolators, and couplers. The system is demonstrated in a 16QAM C-band WDM scenario over 720 km.
