Abstract: PURPOSE: A polarization mode dispersion emulator is provided to improve the reproducibility of polarization mode dispersion by changing a minimum polarization mode dispersion value of a polarization maintaining fiber loop and the number of loop to set a desired resolving power and a maximum polarization mode dispersion. CONSTITUTION: Fiber loops(410) having a constant polarization mode dispersion are melt-connected to each other between single mode fibers(420). A value of polarization mode dispersion of the respective single mode fiber(420) is very smaller than that of the respective fiber loops(410). The other end of each of the single mode fiber(420) is connected to each of stepping motors(430). The stepping motors(430) rotate one of the fiber loops(410). A controller(440) generates an electric signal for driving the stepping motors(430).

Abstract: A polarization mode dispersion (PMD) emulator is disclosed which can easily replicate PMD effect in a fiber span. The PMD emulator of the present invention comprises: at least two sections of polarization maintaining (PM) fiber, each having a predetermined PMD value; mechanical twisting means which twist one of neighboring ones among the PM fiber sections; a single mode fiber spliced in between neighboring PM fiber sections; wherein the single mode fiber has a small PMD value negligible compared to any of the PM fiber sections. According to the present invention, PMD effect can easily be replicated in the field of experiments studying PMD effect of a real fiber span.
