Tunable Optical Filters
OPTICAL FILTERS

 

The Alnair Tunable Optical Filters come in either a manual or computer controllable bandpass filter benchtop versions with an independently tunable center wavelength in the C or C+L band and a variable pass-band bandwidth as narrow as 0.1 nm to as wide as 15 nm. They features an ideal flat top profile with an extremely sharp roll-off at the filter edges of >150 dB/nm, providing a strong out of band suppression of typically 50 dB and a negligible chromatic dispersion within the band pass. Main applications for these tunable filters  include:

Narrow-band selection/filtering of DWDM
Wide-band filtering of CWDM/OTDM
Out-of-band ASE noise suppression
Automated quality control systems
