为了满足人们对信息日益增长的需求,干线光通信系统正在朝长距离、高速率密集波分复用(DWDM)系统演进。此时,光纤的色散及非线性对系统的影响日益突出。光纤色散使光脉冲在传输中时域展宽,导致通信系统的误码增加,限制了系统的无中继传输距离。因此,如何经济有效的对色散进行补偿,成为人们研究的重点之一。随
In order to meet the growing demand for information, trunk optical communication systems are evolving towards long-distance, high-rate dense wavelength division multiplexing (DWDM) systems. At this moment, the influence of dispersion and nonlinearity of the optical fiber on the system becomes more and more prominent. The dispersion of optical fiber broadens the time-domain of light pulse in transmission, which leads to the increase of bit error rate of communication system and limits the system’s relayless transmission distance. Therefore, how to compensate chromatic dispersion economically and effectively has become one of the focuses of people’s research. With
