CVF-200 is the motorized version of the latest advance tunable
optical filters, BVF-200, based on our flexible optical filter tuning technologies.
It can be operated in stand-alone mode via front panel control, or externally
controlled via the USB/RS232 port with a high wavelength precision and
repeatabilty.
The center wavelength is tunable over the entire C-band from
1525nm to 1570nm, and the filter bandwidth is independently tunable from
0.1nm to 13nm. The filter response of the CVF-200 is an ideal flat-top
profile with a very sharp roll-off > 150dB/nm at the filter edges.
The CVF-200 offers a low insertion loss of typically <4dB,
and a low polarization sensitivity. More importantly, the CVF-200 also
exhibits an extremely low chromatic dispersion within its passband, making
it an ideal and flexible tunable filter for various demanding laboratory
or factory automation applications requiring full tunability in optical
filtering.
Bandwidth variable from 0.1nm to 13nm Wavelength tunning range from 1525nm to 1570nm Ideal flat-top filter response with sharp roll-off > 150dB/nm Side-mode suppression of typically 50dB Low chromatic dispersion within passband <1ps/nm Low insertion loss, low polarization
sensitivity Manually contolled via front panel or externally controlled with USB/RS232.
Applications
Filter for factory automation and automated device tests Narrow-band filtering for DWDM, CWDM channel filtering Optical signal selection/rejection with high suppression ratio Dispersion free spectral filtering for short pulses Applications requiring variable passband Adaptive and automated filtering of optical signals
