Alnair Labs CVF-220
The CVF-220 is the an electrically-controllable optical bandpass filter with an independently tunable center-wavelength over C or C + L band, and a variable passband bandwidth from 0.1nm to 15nm. The CVF-220 features an ideal flat-top profile with and extremely sharp roll-off at the filter edges of > 150dB/nm, providing a strong out-of-band suppression of typically 50dB and a negligible chromatic dispersion within the passband.
The CVF-220 can automatically track the peak wavelength of the input signal and displays filter output power. When connected to a PC, the CVF-220 can be used to take optical spectrum with 0.1nm solution. The unit can be operated via the front-panel or remotely via USB or GPIB.
