Mini Gain Flattening Filter for EDFA
Mini GFFM Series
Product Description
Oplink’s Mini Gain Flattening Filters for Erbium-Doped Fiber Amplifiers (ED-
FAs) 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 system. All Oplink products are epoxy-free in the optical path.
