我们通过数值模拟分析了一种新的调制格式：适用于广域100-Gb/S应用的序列暗孤子的性能。当受到典型的广域网络损伤时，我们将其与传统的暗孤子、幅度调制相移键控(也称为双二进制)、不归零和归零调制格式的性能进行了比较。结果表明，该器件具有较强的色散和偏振模色散容限，同时保持了较高的光谱密度，适合于超密集波分复用应用中的强滤波要求。可以使用40-Gb/S应用的商用组件来生成该SD，并且与其他100-Gb/S电时分复用系统相比，该系统具有成本效益。
We analyze the performance through numerical simulations of a new modulation format: serial dark soliton (SDS) for wide-area 100-Gb/s applications. We compare the performance of the SDS with conventional dark soliton, amplitude-modulation phase-shift keying (also known as duobinary), nonreturn-to-zero, and return-to-zero modulation formats, when subjected to typical wide-area-network impairments. We show that the SDS has a strong chromatic dispersion and polarization-mode-dispersion tolerance, while maintaining a compact spectrum suitable for strong filtering requirement in ultradense wavelength-division-multiplexing applications. The SDS can be generated using commercially available components for 40-Gb/s applications and is cost efficient when compared with other 100-Gb/s electrical-time-division-multiplexing systems.
