摘要翻译：
支持25、50和100 Gb/s的下一代高速无源光网络（HS-PON）收发器正处于标准化过程的早期阶段。这个过程的一个关键方面是最佳调制格式的选择。为此，各种调制格式在不同物理约束下的性能比较已经在文献中提出，目前仍在进行中。在我们的贡献中，我们详尽地分析了收发器电频率响应形状对2电平脉冲幅度调制(PAM-2)、4电平PAM(PAM-4)、电双二进制调制和光双二进制调制格式性能的影响，这些调制格式在接收机侧具有自适应均衡器。我们通过数值模拟表明，通常使用的-3dB带宽规格是不够的，因为带外电频率响应规格（如-20dB带宽）也对所分析的调制格式的性能有巨大的影响。本文最后给出的-3dB和-20dB带宽的归一化图可用于下一代HS-PON收发器的设计。

英文摘要：
  Next-generation high-speed passive optical network (HS-PON) transceivers supporting 25, 50 and 100 Gb/s are under the early stage of their standardization process. One key aspect of this process is the choice of the best modulation format. To this end, performance comparisons among several modulation formats against different physical constraints have been presented in literature and are still being carried out. In our contribution, we performed an exhaustive analysis on the impact of transceivers electrical frequency response shape on the performance of 2-levels pulse amplitude modulation (PAM-2), 4-levels PAM (PAM-4), electrical and optical duobinary modulation formats with adaptive equalizer at the receiver side. We show by means of numerical simulations that the specification of the typically used -3dB bandwidth is not sufficient, since also out-of-band electrical frequency response specifications (such as the -20dB bandwidth) has a huge impact on the performance of the analyzed modulation formats. The normalized graphs given at the end of the paper in terms of -3dB and -20 dB bandwidths can thus be useful for the design of the next generation of HS-PON transceivers.
