Product Detail
The Fiber Optic Tunable Filter (FOTF) is based on fiber Fabry-Perot interferometer technology. Driven by apiezoelectric 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 wavelength scaning, spectrum analysis, signal selection and noise rejection.
