OPTICAL TRANSMISSION SYSTEM |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To improve wavelength dispersion and a dispersion slope of the whole transmission system applied in a 1.55μm wavelength band. <P>SOLUTION: A dispersion compensation fiber 100 has at least wavelength dispersion of not less than -40ps/km/nm and not more than 0ps/km/nm, and a dispersion slope of not less than -0.5ps/km/nm<SP>2</SP>and not more than -0.1ps/km/nm<SP>2</SP>to the light of the 1.55μm wavelength band, and in the 1.55μm wavelength band, the wavelength dispersion and the dispersion slope of the whole system including the dispersion compensation fiber 100 can be improved by cascading the dispersion compensation fiber 100 and a dispersion shift fiber 500 for compensation at an appropriate length ratio. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
