A dispersion compensating fiber which does not cause an increase in a loss if it is wound in a small reel and has a stable temperature characteristics is provided, wherein, in a wavelength range from dispersion compensating fiber1.53 to 1.63 mu m, a bending loss with a 20 mm bending diameter is 5 dB/m or lower, a chromatic dispersion is -120 ps/nm/km or lower, a cut-off wavelength under a usage condition is 1.53 mu m or lower, an outer diameter of the cladding is 80 to 100 mu m, an outer diameter of a coating is 160 to 200 mu m, and a an adhesive property of a surface of a coating resin is 10 gf/mm or lower. <IMAGE> |
