Fiber Optic Tunable Filter (FOTF Series)

产品详细信息

Product Name: Fiber Optic Tunable Filter (FOTF Series)


The Fiber Optic Tunable Filter is based on fiber Fabry-Perot interferometer technology. Activated by a piezoelectric transducer, the device can be tuned across the entire C + L band. It is ideal for applications in signal selection, noise rejection, and spectrum analysis. Two thermistors are mounted in the filter package for temperature monitoring.
