Abstract
We experimentally demonstrate an ultra-large-capacity, high-spectral-efficiency fiber-wireless-integration system within the V-band (50-75 GHz), employing single-carrier polarization-division-multiplexing 64-ary quadrature-amplitude-modulation (PDM-64QAM) modulation and heterodyne coherent detection. In our demonstrated system, up to a 10-Gbaud (120-Gb/s) PDM-64QAM vector millimeter (mm)-wave signal at 57.2 GHz can be generated with a bit-error ratio (BER) less than the hard-decision forward-error-correction (FEC) threshold of 3.8 × 10-3, while an up to 20-Gbaud (240-Gb/s) PDM-64QAM vector mm-wave signal at 57.2 GHz can be generated with the BER less than the soft-decision forward-error-correction (SD-FEC) threshold of 2 × 10-2. In our demonstrated system, a 10-Gbaud (120-Gb/s) 57.2-GHz PDM-64QAM vector mm-wave signal can also be delivered over a 60-km single-mode fiber-28 (SMF-28) and an 1-m wireless distance with a BER less than the SD-FEC threshold. To the best of our knowledge, this is the first time that an over 100-Gb/s single-carrier wireless mm-wave signal delivery at V-band has been realized.
