Abstract

We experimentally demonstrate radio-over-fiber transmission of 44.4Gb/s 65536-QAM at 25GHz employing 2-bit high-pass delta-sigma modulation. 0.19% EVM is achieved after 10km C-band SSMF transmission, and dispersion-induced RF fading is mitigated by differential skew-enabled spectral shaping.

在25GHz频段支持65536-QAM的光纤无线传输，具有高通Delta-Sigma调制和射频衰落缓解

我们通过实验演示了采用2位高通δ - σ调制的25GHz下44.4Gb/s 65536-QAM的光纤无线电传输。在10km的c波段SSMF传输后，EVM达到0.19%，并且通过使能微分偏谱整形减轻了色散引起的射频衰落。
