1.12-Tb/s 32-QAM-OFDM superchannel with 8.6-b/s/Hz intrachannel spectral efficiency and space-division multiplexing with 60-b/s/Hz aggregate spectral efficiency

We demonstrate the generation of a 1.12-Tb/s superchannel with a net intrachannel-spectral-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.
