OPTICAL FIBER, DISPERSION COMPENSATOR COMPRISING THE SAME, OPTICAL TRANSMISSION LINE, AND OPTICAL TRANSMISSION SYSTEM |
| 摘要 |
An optical fiber having a refractive index distribution structure composed of a core and a two-layer clad including an innermost layer and an outermost layer satisfying the inequalities 0.8% </= DELTA 1 </= 1.3% and -0,7% </= DELTA 2 </= -0.4% ( DELTA 1 where 1 is the relative refractive -index difference of the core to the outermost layer of the clad, DELTA 2 is the relative refractive-index difference of the innermost layer of the clad to the outermost layer of the clad, wherein the optical fiber also satisfies the inequalities -20 </=D < 0, -0.1 </= S < 0, and 0 < (D/S) </= 200 in a specific predetermined wavelength band having a band width of more than 20 nm in the 1.5 mu m band where D (ps/nm/km) is the wavelength dispersion at a specific wavelength in the 1.5 mu m band and S (ps/nm<2>/km) is the dispersion slope.
