Fabry-Perot (F-P) etalon (100GHz finesse: 40) WLFE-2-1550-100-40-SM-0.9/1.0-FC/APC

Idealphotonics' Fabry-Perot etalons are based on free-space 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 a transmission spectrum, the 3-port type provides transmission and reflection spectra, 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 etalon wavelength can cover the C-band, including single mode and polarization-maintaining fiber. The free-space range (FSR) and finesse (F) of the etalon can be customized according to customer requirements. Widely used in optical communications, fiber grating sensors, and tunable fiber laser.

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

Application area：Wavelength lockers、 Wavelength division multiplexing telecommunication networks、 Handheld spectrum analyzers、 Fiber Bragg grating sensing systems、 Tunable filter lasers、 Tunable filters
