6×56-Gb/s Mode-Division Multiplexed Transmission over 33-km Few-Mode Fiber Enabled by 6×6 MIMO Equalization
15 August 2011
Mode-division multiplexing over 33-km few-mode fiber is investigated. It is shown that 6×6 MIMO processing can be used to almost completely compensate for crosstalk and intersymbol interference due to mode coupling in a system that transmits uncorrelated 28-GBaud QPSK signals on the six spatial and polarization modes supported by a novel few-mode fiber. © 2011 Optical Society of America OCIS codes: (060.0060) Fiber optics and optical communications; (060.1660) Coherent communications; (060.2360) Fiber optics links and subsystems; (060.2400) Fiber properties; (060.4230) Multiplexing; (030.4070) Modes.
