Gain flat filter GFF3:1270～1330nm GFF5/GFFP5:1525～1570nm
Gain flat filter is designed to connect to the output ports of EDFA or PDFA. By introducing additional signal loss at higher gain wavelengths, it flattens the gain spectrum of EDFA, making it ideal for applications requiring consistent gain across broad spectral ranges. The gain spectrum of fiber amplifiers depends on input power; when input power decreases, the gain variation within the operating wavelength range becomes more pronounced.
