Product information "FPS-003 Phase Shifter"
780-1550 nm; Total Phase Shift >55π; IL <0.5 dB; RL >55 dB; PDL <0.05 dB; Residual Amplitude Modulation ±0.01 dB
Lunas 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 Lunas 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.
