Fiber optic phase shifter

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 advantage of the all-fiber construction is that insertion loss and back reflection are reduced to near zero. FEATURES Low insertion loss Low residual amplitude modulation NoTail™ version available APPLICATIONS Precision phase tuning or phase modulation in fiber interferometers and sensor systems
