Fiber Phase Shifter (FPS-003)
The FPS-003 all fiber phase shifter/modulator combines a wide modulation bandwidth (up to 60 kHz) with low half-wave voltages to create a long-range device that can be driven by standard function generators. Like General Photonics’ other phase shifters, it employs all fiber construction and has low insertion loss and back reflection. In addition to fiber sensor systems, this compact device is ideal for fiber laser systems, fiber resonators, and fiber interferometers for precision phase tuning or phase modulation.
