Fiber Phase Modulator/Shifter
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.
The FPS-003 is a small, piezo-driven phase shifter that works by stretching a length of fiber. Like other FPS phase shifters, it employs all fiber construction and has low insertion loss and back reflection. It has a low half- wave voltage and a higher frequency range and resonance frequency than the FPS-002.
