Gain Flattening Filter

 

Gain Flattening Filters for Erbriun-Droped Fiber Amplifiers (EDFAs) are based on thin-film filter technology and metal bonding micro-optics packaging. The Gain Flattening Filters provide in line compensation of the spectral gain profile of EDFAs. This device is used in high-power applications in DWDM systems.

 

The products are Telcordia GR-1221/1209-CORE qualified, and RoHS compliant.
