| 摘 要： | 主要研究在波长间隔50GHz的密集波分复用系统中,112Gbit/s偏分复用差分四相移键控信号在不同速率的相邻信道影响下经过长距离传输后的非线性容忍度。实验结果表明,112Gbit/s信号结合43Gbit/s信号或者10Gbit/s信号传输时系统得到较好的非线性容忍度,验证了在严重的非线性效应存在的情况下同步传输系统的可行性。 |

| Abstract: | Nonlinear tolerance of 112 Gbit/s polarization-multiplexed differential quadrature phase-shift keying signal over long-haul transmission with different types of neighboring channels, and with a cascade of 50-GHz grid is increased. The result indicates considerable tolerance to nonlinear effects is observed and proves the feasibility of 112 Gbit/s overlaying existing 10 Gbit/s or 43 Gbit/s commercial systems despite the presence of strong cross-phase modulation. |
| Keywords: | optical communications nonlinear effects cross-phase modulation (XPM) polarization-multiplexed differential quadrature phase-shift keying coherent detection dense wavelength division multiplexing (DWDM) |
