Abstract
We leverage sideband modulation-based bidirectional scheme to separate the transmitter-side IQ imbalance and boost the SNR to 30.8dB. We experimentally demonstrate high-capacity coherent analog RoF fronthaul achieving 27.6Tb/s(=12λ×2.089Tb/s) CPRI-equivalent rate and 512-QAM over 10-km SSMF.
