DISPERSION SHIFT OPTICAL FIBER |
摘要 |
<p>The present invention relates to a dispersion-shifted optical fiber comprising a structure for reducing optical loss and restraining nonlinear phenomena from occurring. In order to restrain the nonlinear phenomena from occurring, this dispersion-shifted optical fiber has an effective area of 70 mu m<2> or more with respect to light whose center wavelength falls within the range of 1500 to 1600 nm, and the peak position where optical power of the light in a fundamental mode is maximized is radially shifted from a center of a core region by a predetermined distance. Also, in this dispersion-shifted optical fiber, optical power at a position radially separated from the peak position by a distance which is five times the center wavelength of the light becomes 1/100 or less of the optical power at the peak position. As a consequence of this structure, bending loss can effectively be reduced. <IMAGE></p> |
