How Premium Gain Flattening Filters (GFF) Improve EDFA Performance
Gain flattening filters (GFFs) are used to smooth out unequal intensities in a signal spectrum. Common applications for GFFs are in modulating the output of laser amplifiers, including erbium-doped fiber amplifiers (EDFA), where the wavelength-dependent gain spectrum...
The Application of WDM Channel Skip Filters
Channel skip filters are components added to wavelength division multiplexing (WDM) add/drop modules — in both coarse wavelength division multiplexing (CWDM) and dense wavelength division multiplexing (DWDM) applications — to facilitate band splitting and to manage multiple ITU channels.
These filters feature narrow transitions from pass band to blocking band, minimizing lost channels while maintaining high spectral efficiency (i.e., limiting insertion loss) since the express channels undergo only one reflection.
How Compensating Gain Flattening Filters Improve PPEF Performance
How Compensating Gain Flattening Filters Improve PPEF Performance. Iridian’s premium compensating GFFs offer a means to better control PPEF using what is known as the multi-design compensating method.
