We demonstrate the generation of a 1.12-Tb/s superchannel with a net intrachannelspectral-efficiency (ISE) of 8.6 b/s/Hz, and its transmission over a 76.8-km seven-core-fiber using space-division-multiplexing, achieving a record aggregate ISE of 60 b/s/Hz per fiber. OCIS: (060.1660) Coherent communications; (060.5060) Phase modulation; (060.2330) Fiber Optics Communications.
