Fiber Phase Shifter FPS-003

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.
