本系列产品为Broad band FBG(宽带fiber bragg gratting)。Using the technique of "chirped" Fiber Bragg gratings, we are able to provide FBGs with a very broad bandwidth and with a high rejection.
We can provide a wide range of center wavelengths, bandwidths, and reflectivities.

Broad band FBG（宽带fiber bragg grating） 主要应用场合为：

• WDM 1300/1550nm band rejection filter
   
• ASE filtering, noise suppres- sion
   
• In-fiber mirrors
•
