A remote-node heterodyne millimeter-wave radio-over-fiber (MMW-RoF) link was proposed by a dual-mode optical carrier with orthogonal polarizations and single-wavelength modulation, which effectively suppresses the chromatic dispersion and four-wave mixing. For optical wireline transmission, the bit error rate (BER) of a 25-km single-mode fiber (SMF) transmitted baseband 24-Gbit/s 64-QAM OFDM can be improved to 5.9×10 with an error vector magnitude (EVM) of 7.1%. Moreover, the beat 35-GHz MMW carrier with a 32-dB carrier-to-noise ratio was generated for wireless transmission. The BER and EVM of passband 8-Gbit/s 16-QAM OFDM at 35-GHz MMW carrier were 3.4×10 and 17.1%, respectively, after 25-km SMF and 1.6-m free-space transmissions.
一种远程节点外差式毫米波光纤无线（MMW-RoF）链路由具有正交偏振和单波长调制的双模光载波提出，该链路有效抑制了色散和四波混频。对于光纤有线传输，25公里单模光纤（SMF）传输基带24-Gbit/s 64-QAM OFDM的误码率（BER）可提高到5.9×10，误差矢量幅度（EVM）为7.1%。此外，还生成了具有32 dB载噪比的35-GHz毫米波载波用于无线传输。经过25公里SMF和1.6米自由空间传输后，35-GHz毫米波载波上的8-Gbit/s 16-QAM OFDM通带的BER和EVM分别为3.4×10和17.1%。
