Gain Flattening Filters (GFF)
Equipped with cutting-edge optical coating systems and its industry-leading and proprietary optical thin film technology, particularly in GFF design, coating process and optical monitoring, Lightwaves2020 manufactures and supplies custom-GFF filters for various demanding applications.
 Capabilities
- >Peak-to-valley in the IL profile as high as more than 10dB
- >For typical GFF, the common peak-to-peak error function is below 0.3dB
- >Able to make the GFF with transmission isolation at both sides of the profile
Features
- >Small peak-to-peak error function, typical < 0.3dB
- >Low insertion loss
- >Small fast ripples
- >Low polarization dependent loss (PDL), typical < 0.5dB
- >Low temperature dependent loss (TDL), typical < 0.05dB
- >Low temperature dependent wavelength shift, typical < 1.0pm/oC
- >Angle tuning (up to 3 deg AOI)
- >Telcordia Compliant
- >Dielectric hard coating and excellent environmental stability and reliability
