DISPERSION FLAT OPTICAL FIBER |
| 摘要 |
<p>The present invention aims at providing a dispersion-flattened optical fiber which is suitable for wavelength-division multiplexing soliton transmission utilizing an optical amplifier and the like and has a structure for effectively restraining nonlinear optical phenomena from occurring. The dispersion-flattened optical fiber according to the present invention has, as characteristics at a wavelength of 1550 nm, a dispersion with an absolute value of 5 ps/nm/km or less, an effective cross-sectional area of 45 mu m<2> or more, a dispersion slope of 0.03 ps/nm<2>/km or less, and a cutoff wavelength of 1.0 mu m or more at a length of 2 m. <IMAGE></p> |
