A fiber link with pupil slicer (FPS) consists of a lens array and 7 fibers, and an optics coincidencing output F-number to the input F-number of HDS. The FPS opens up possibility for opening the entrance aperture of the high dispersion spectrogragh (HDS) of Subaru telescope from 0.8 to 0.27 aresecond to attain resolving power three times as high as 150, 000 in comparison with entrance slit width. We present two concrete examples for applying the fiber, method for measuring the degree of fiber ratio degradation (FRD) of an optical fiber and spectroscopy observation of spectral type stars.
