FBG is widely used in various occasions of optical communication, and this type of product can be customized as DWDM FBG according to needs
Fiber Bragg gratings are components for a wide range of applications in optical communications. The FBGs act there as in-fiber narrow band filters. This series of products is FBG (DWDM FBG) applied to DWDM
DWDM FBG mainly includes the following applications:
DWDM technology for 2.5 Gbps and 10 Gbps systems
ASE filtering
Add/Drop-multiplexers for 100GHz and 50GHz channel spacing
