光纤光栅在全光通信网中的应用

随着社会对通信业务需求的不断增加，基于DWDM的全光网络已成为未来光通信的发展趋势，光纤光栅具有附加损耗小，体积小，能与光纤很好地耦合，可与其他光纤器件融成一体等特性，这将使光纤光栅成为未来全光网中的基石，从目前的研究来看，光纤光栅已经能够为全光通信系统不光源，光放大，色散补偿，OTM（光终端复接器），OTDM（光时分复用），OXC（光交叉连接）等等关键部件提供优秀的解决方案。

Applications of fiber Bragg grating in all-optical networks

Because of the continuously increasing need for broadband communication, all optical network(AON) based on WDM technology is considered as the trend of the future network development. Due to its perfect characteristics such as low excess loss, small volume, good coupling with optical fiber, compatibility with other fiber optic devices, fiber Bragg grating will become the key block in the future all optical networks. At present fiber grating has had the capability to provides excellent solutions for many key devices in all optical communications systems. These devices include optical source, optical amplifier, dispersion compensator, OTM, OTDM, OXC etc.
