MIMO-based Signal Processing in Spatially Multiplexed 112-Gb/s PDM-QPSK Signals for Strongly-Coupled 3-Core Fiber
18 September 2011
We experimentally demonstrate 6 × 6 coherent multiple-input multiple-output (MIMO) crosstalk mitigation in simultaneous transmission of 3 spatially multiplexed 112-Gb/s PDM-QPSK channels over 24 km of a strongly-coupled 3-core fiber. The crosstalk in the fiber which is about -4 dB is almost completely mitigated by the MIMO processing. OCIS codes: 060.4510, 060.1660, 060.2280, 040.1880, 060.4230.
