中文摘要：

随着信息技术的飞速发展,通信网络中的数据传输量越来越大,WDM光网络已经成为长途传输骨干网络的首选,但是,各种大数据量业务的兴起,使得WDM光网络中本来就极其宝贵的波长资源更加显得不足.近年来,为了更充分地利用光频谱资源,出现了一种新的灵活栅格光网络.对基于光纤通信的灵活栅格光网络技术进行了研究,探讨了灵活栅格光网络特点,分析了灵活栅格光网络中频谱碎片的优化问题.最后,讨论了灵活栅格光网络中频谱资源重构需要克服的困难.

英文摘要：

With the rapid development of information technology, the amount of data transmission in the communication network is bigger, and the WDM optical networks has become the first choice for long-distance transmission backbone network. However, due to the rise of various large amounts of data, it made extremely precious wavelength resources more insufficient in WDM optical networks. In recent years, in order to make full use of the optical spectrum, there is a new flexible grid optical network. Flexible grid optical network technologies, based on the fiber communication, are studied. Characteristics of flexible grid optical network are discussed, and the optimization problems of spectrum fragments are analyzed. Finally, it discussed the difficulties that need to be overcome for spectrum defragmentation in flexible grid optical network.
