The FPTF Fiber Fabry-Perot Tunable Filter features a narrow linewidth of ~0.1nm,a low loss of <0.3dB, wide tuning range of ~100nm. It is based on a fiber tip gap etalon cavity configuration that is movable by a piezoelectric actuator. We offerthree  wavelengths range of  1550nm-1600nm. The device is vibration-insensitive. The performance of FPTF is a trade-off between the parameters; for example, if select 0.1nm linewidth, then the tuning range is only 10nm. The FPTF is a cost-effective solution for wavelength scanning applications with a speed up to 1kHz. The device is drifting that requires feedback control to stabilize.
