<p><P>PROBLEM TO BE SOLVED: To provide a design method of a dispersion compensating fiber in which the absolute value of a dispersion value and the value of structure tolerance are set large and to provide the dispersion compensating fiber. <P>SOLUTION: The value of a structure tolerance is determined so that the product of the dispersion value and yield becomes greater than a prescribed value and the structure parameters of the dispersion compensating fiber are determined to realize the structure tolerance value. The dispersion compensating fiber is provided with a first core 11, a first clad 12, a second core 13 and a second clad 14 and the structure tolerance is set to 2 to 8% and the dispersion value is set to -1,100 to -200 ps/nm/km. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
