Low-loss and Low-crosstalk All-fiber-based Six-mode Multiplexer and Demultiplexer for Mode-Multiplexed QAM Signals in C-band

We show all-fiber-based six-mode multiplexer and demultiplexer. The OSNR penalty due to six-mode multiplexing is suppressed to be 2 dB in DP-16QAM with 12×12MIMO and 3 dB in DP-QPSK even with 4×4/2×2MIMO over C-band.
