摘要

正交频分复用(OFDM)是未来高速光接入网的一个很有前途的选择。由于OFDM信号分别通过电子数模转换器(DAC/ADC)和模数转换器(DAC/ADC)在数字域通过快速傅里叶变换(FFT)产生和解调，因此OFDM信号带宽受到DAC/ADC采样率的限制。在这项工作中，我们提出了在未来高速PON中使用全光OFDM的可行性。全光OFDM是另一类依赖于全光产生或解调正交子载波的光多载波传输。因此，可以很容易地实现高数据速率。介绍了一种采用全光OFDM超级信道(SC)的200gb /s OFDMA-LR-PON。除了光纤有线传输外，还演示了w波段(100 ghz)毫米波(MMW)无线传输，以支持楼宇内移动宽带业务。

Direct-detection all-optical OFDM superchannel for long-reach PON

Orthogonal-frequency-division-multiplexing (OFDM) is a promising candidate for the future high-speed optical access networks. As the OFDM signal is electronically generated and demodulated by fast Fourier transform (FFT) in the digital domain via electronic digital-to-analog and analog-to-digital converters (DAC/ADC) respectively, the OFDM signal bandwidth is limited by the sampling rate of the DAC/ADC. In this work, we present the feasibility of using all-optical OFDM for the future high-speed PON. All-optical OFDM is another class of optical multiple carrier transmission that relies on all-optically generated or demodulated orthogonal subcarriers. Hence, high data rate can be easily achieved. A 200 Gb/s OFDMA-LR-PON using all-optical OFDM super-channel (SC) is demonstrated. Apart from the optical wired transmission, w-band (100-GHz) millimeter-wave (MMW) wireless transmission is also demonstrated to support the in-building mobile broadband services.
