Abstract :
We present the first experimental time- and frequency-domain MIMO channel matrix characterization versus distance for 6×28Gbaud recirculating loop transmission over 40×25km FMF. Beyond 10dB time- and frequency-domain singular-value spreads are observed, motivating nonlinear MIMO equalization.
