Hybrid GFF with Laser Blocking
This Hybrid GFF combines the functionality of a pump laser blocker and of a gain flattening filter in order to reduce the number of filters used in the package. These characteristics are obtained without compromise to performance. The GFF is in the typical C-Band range of 1530-1565nm and the 980nm pump is blocked at a level >15dB.
