摘要
Abstract
In this paper, we combine the Space Division Multiplexing (SDM) and Dense Wavelength Division Multiplexing (DWDM) technologies to experimentally demonstrate 560 Tbit/s coherent optical dual-polarization DFT-s Orthogonal Frequency Division Multiplexing (OFDM) 32 Quadrature Amplitude Modulation(QAM) signal transmission over 10 km single-mode 7 core fiber.The system uses 16 independent laser sources to generate 375 DWDM channels with 25 GHz grid.The channel capacity for single core is 85.91 Tbit/s and the total channel capacity for the 7 core fiber is 601.36 Tbit/s.After excluding the 7% Forward Error Correction(FEC) which aiming at the threshold of 3.8×10-3, the net data rate is 562.02 Tbit /s with spectral efficiency of 59.95 bit/s/Hz.关键词
