Fiber Optic Tunable Filter (GK-FOTF Series)

The Fiber Optic Tunable Filter (FOTF) is based on fiber Fabry-Perot interferometer technology. Driven by a piezoelectric actuator, the device can be tuned across a wide band range. New techniques have been applied in FOTF to guarantee high accuracy fiber alignment and to support fast tuning rate. It is an ideal solution for applications in wavelengthscaning, spectrum analysis, signal selection and noise rejection.
