ORTE 2x2 High Reliability Gain Flattening Filters (GFF)
The GFF gain flat filter is based on the thin film filter technology, which is specially designed and manufactured according to the erbium-doped fiber emission spectrum. The main function of GFF gain flattening filter is to flaten the emission spectrum of erbium-doped fiber, so that the output spectrum of the light source can achieve good flatness in the whole band.
