Thin Film Gain Flattening Filter
Key Features
• Deep profiles (> 20 dB)
• Steep profiles (> 2.5 dB/nm)
• Low error function
• Power handling up to 2000 mW
Applications
• Long-haul terrestrial
• Metro
• Raman
• C, L, and S band
Gain flattening filters (GFFs) flatten the gain profile in optical amplifiers by
selectively removing excess power.
The JDSU thin film GFF offers an excellent match to the target loss profile with low
excess loss and error function, even for exceptionally deep (>20 dB) and steep GFF
(>2.5 dB/nm) profiles.
Customized thin film GFFs are available in the C, L, and S bands. All JDSU thin
film GFFs fulfill Telcordia GR-1221 requirements.
