Express 20, 2668-2680 (2012)http://hdl.handle.net/10347/21362We demonstrate mode-division multiplexed WDM transmission over 50-km of few-mode fiber using the fiber’s LP01 and two degenerate LP11 modes. A few-mode EDFA is used to boost the power of the output signal before a few-mode coherent receiver. A 6×6 time-domain MIMO equalizer is used to recover the transmitted data. We also experimentally characterize the 50-km few-mode fiber and the few-mode EDFAeng© 2012 Optical Society of Americajournal article10.1364/OE.20.0026681094-4087open access
