We experimentally demonstrate a record 400G optical wireless integration system simultaneously delivering 2 × 112 Gb/s two-channel polarization-division-multiplexing 16-ary quadrature amplitude modulation (PDM-16QAM) signal at 37.5 GHz wireless carrier and 2 × 108 Gb/s two-channel PDM quadrature phase shift keying (PDM-QPSK) signal at 100 GHz wireless carrier, adopting two millimeter-wave (mm-wave) frequency bands, two orthogonal antenna polarizations, multiple-input multiple-output (MIMO), photonic mm-wave generation and advanced digital signal processing (DSP). In the case of no fiber transmission, the bit error ratios (BERs) for both the 112 Gb/s PDM-16QAM signal after 1.5 m wireless delivery at 37.5 GHz and the 108 Gb/s PDM-QPSK signal after 0.7 m wireless delivery at 100 GHz are below the pre-forward-error-correction (pre-FEC) threshold of 3.8 × 10(-3). To our knowledge, this is the first demonstration of a 400G optical wireless integration system in mm-wave frequency bands and also a capacity record of wireless delivery.
我们通过实验展示了一种创纪录的400G光无线集成系统,该系统采用两个毫米波(mm波)频段、两个正交天线极化、多输入多输出(MIMO)、光子毫米波产生和先进数字信号处理(DSP),同时在37.5GHz无线载波上传输2×112Gb/s的两通道偏振分复用16进制正交幅度调制(PDM-16QAM)信号,并在100GHz无线载波上传输2×108Gb/s的两通道PDM正交相移键控(PDM-QPSK)信号。在无光纤传输的情况下,37.5GHz下1.5m无线传输后的112Gb/s PDM-16QAM信号以及100GHz下0.7m无线传输后的108Gb/s PDM-QPSK信号的误码率(BER)均低于前向纠错(pre-FEC)阈值3.8×10(-3)。据我们所知,这是毫米波频段400G光无线集成系统的首次演示,也是无线传输容量的一项纪录。
