It is known that there is a slight difference of zero dispersion along an optical fiber link, because the link is concatenated with lengths of fibers.
由于光纤线路由多根光纤连接而成，因此沿整个线路零色散波长就稍有差别。
The fiber laser takes the advantage of high accurate wavelength, fast tuning and low cost. More widely wavelength tuning can be achieved by adding the numbers of concatenated fiber Bragg gratings.
这种光纤激光器具有波长调节准确，调谐速度快，成本低的优点，可用于作为多波长光纤传输系统的发射光源或系统检测光源，进一步增加级联光栅的组数可实现更大调谐范围。
