<p><P>PROBLEM TO BE SOLVED: To provide a method of designing an optical fiber transmission system that is lower cost, has a longer transmission range and increases a transmission capacity, by reducing an amount of dispersion accumulated over the whole transmission length of an undersea cable. <P>SOLUTION: The optical fiber is described which has a relatively large effective sectional area, large negative dispersion coefficient, and relatively low attenuation. These optical fibers are advantageously paired with positive dispersion coefficient optical fibers for blockless undersea cables. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
