Manually tunable fiber Bragg grating filter

Xiaoxiao Photon's tunable fiber Bragg grating filter (OETFG-200) can provide a stable adjustable range, simple structure, high resolution, and long lifespan. This adjustable filter adopts Fiber Bragg Grating (FBG) technology, which can be used for both transmission mode and reflection mode, or only for reflection mode (as required). As an option, a fiber optic circulator can be integrated to provide a bandpass signal for the output port. The cyclist can be used in the range of 1060nm, 1310nm, and 1550nm. The band stop option without the need for a loop protector is also available. In the bandstop version, the communication signal is reflected to the input end.
