The FPS-001 is an all fiber device that shifts or modulates phase by up to 15π at frequencies from DC to 20 kHz.
The FPS-001 is a small, piezo-driven phase shifter that works by stretching a length of fiber. It can provide several π phase shift at frequencies up to 20 kHz. Because the optical path is all in fiber, the device has minimal insertion and return loss. The FPS-001 uses a straight fiber rather than fiber wound on a frame, so the optical path length in fiber is exactly the length of the device from connector tip to connector tip, and can be minimized by controlling the length of the pigtails or by using a NoTail version.
