IGFF Device
Auxora's Isolator Gain Flattening Filter (IGFF) is a filter-based device which features ultra low insertion loss, super thermal stability and excellent reliability. The device is a combination of one polarization insensitive isolator and one GFF device based on lead-free packaging platform without epoxy on the optical path. The GFFs provide in-line compensation of the spectral gain profile of EDFAs, and can be used for high-power applications in DWDM system.
