Abstract

为了解决传输高阶正交幅度调制（QAM）信号时的非线性损伤问题，提出了一种基于Delta-Sigma调制（DSM）的高阶QAM传输系统。通过采用1-bit量化的DSM，成功将携带有高阶QAM的离散多音调制（DMT）信号量化编码为开关键控（OOK）信号，实现了高阶QAM信号在O波段强度调制/直接检测（IM/DD）系统中的传输。由于DSM拥有较高的量化信噪比，系统最高支持满足软判决2.4×10-2阈值的4096QAM信号的传输。特别地，通过采用预均衡技术，成功实现了50/100 Gbaud DSM信号分别在O波段的50/15 km的传输。实验演示了高速DSM信号在O波段的传输系统，为高阶QAM信号在IM/DD链路的传输提供了解决方案，同时也为未来基于DSM技术的高速移动前传方案设计提供了参考。

期刊介绍： Researching is owned by Chinese Laser Press (CLP), which is established by Shanghai Institute of Optics and Fine Mechanics and Chinese Optical Society in 2009. Nowadays, CLP publishes 11 journals and manages three online platforms. Journal publishing activities include both traditional and digital models, and the first journal can be traced back to 1964. The CLP Online Library includes the CLP journals and partnered ones in China, and provides literature and intelligence services for users. The product platform, named as OEShow, connects sellers and buyers of optoelectronics products. Researching (formerly known as The CLP Publishing) is featured with stable operation and leading technology, collects CLP journals and partnered optics and photonics journals, and provides readers an optical publishing platform with global influence. CLP is on the way of building a modern publishing group combining traditional business and digital publishing.
