Fabry-Perot (F-P) etalon (25GHz finesse: 7.5)

Our Fabry-Perot etalons are free-space based Fabry-Perot etalons. They provide periodic wavelength comb transmission. They include 2-port transmission type, 3-port transmission/reflection type and 4-port transmission type. The 2-port type provides transmission spectrum, the 3-port type provides transmission and reflection spectrum, and the 4-port type provides a phase delay (when the same signal is input into the two input ports, there is a phase delay at the two output ports). Our company's Fabry-Perot etalons can cover the C-band wavelength, including single-mode and polarization-maintaining fibers. The free-space range (FSR) and finesse (F) of the etalons can be customized according to customer requirements. They are widely used in optical communications, fiber Bragg grating sensors, and tunable fiber lasers.

Product features：Available in X, O, S, C, and L bands、 Compact passive package、 Low insertion loss、 SM or PM fiber pigtails、 High optical power handling
