摘　　要：近年来网络数据流量呈现爆发式增长,光纤通信系统作为全球宽带网络的基础,已承载着90%以上的数据流量,并继续朝着多维、超大容量、超长距离等方向发展。搭建了一套模拟跨洋传输的超高容量距离积单模光纤传输系统实验平台。在发射端,根据传输信道光信噪比,采用不同信息熵产生不同传输速率的偏振复用概率整形16阶正交幅度调制光信号。光纤传输链路是由国产超低损大有效面积光纤与国产超宽带低噪声C波段掺铒光纤放大器组成。整个系统基于129个波长信道(波长范围为1529.8~1568.2 nm)进行了传输验证,得到的传输容量为28.09 Tbit/s,传输距离为12000 km,总容量距离积达到337 Pbit·s^(-1)·km。The network data traffic has exhibited an explosive growth trend in the last few years.As the foundation of the global broadband network,optical fiber communication systems have carried more than 90%of the data traffic and developed towards multi-dimension,ultra-large capacity,and ultra-long distance.In this paper,we build an ultra-high capacity-distance product single-mode fiber transmission experimental system to simulate transoceanic transmission.In the transmitter,according to the optical signal-to-noise-ratio of the transmission link,different information entropies are used to generate polarization multiplexing probability shaping 16-order quadrature amplitude modulation signals with different transmission rates.The fiber transmission link is composed of the ultra-low loss large-effective-area fiber and the ultrawideband low-noise C-band erbium-doped optical fiber amplifier.The experimental system uses 129 wavelength channels(the wavelength range is 1529.8 nm to 1568.2 nm)and realizes the transmission capacity of 28.09 Tbit/s and the transmission distance of 12000 km.Therefore,a capacity-distance product of 337 Pbit·s^(-1)·km is achieved.
