The optical fiber coil has a coiled part constituted by a dispersion-compensating optical fiber wound like a coil while being in a bundle state with its winding distortion substantially eliminated. The housing is filled with a resin surrounding the coiled part of the optical fiber coil, whereas the coiled part is held by the resin. The dispersion-compensating optical fiber constituting the optical fiber coil has a chromatic dispersion of −140 ps/nm/km or less at a wavelength of 1.55 μm, whereas the housing has a volume of 500 cm3 or less. This configuration allows the dispersion compensator to attain an accumulated chromatic dispersion of −1200 ps/nm/km or more but less than −600 ps/nm at a wavelength of 1.55 μm.

摘要： The present invention relates to a dispersion compensation unit capable of compensating for both the chromatic dispersion and dispersion slope of a non-zero dispersion-shifted optical fiber. The dispersion compensation unit is formed by winding a first optical fiber and second optical fiber into coil shapes and storing them in a case. The first optical fiber has a negative chromatic dispersion D1 and a negative dispersion slope S1 at a wave length in use. The second optical fiber has a positive chromatic dispersion D2 and a positive dispersion slope S2 at the wavelength in use.
