ABSTRACT METHOD AND APPARATUS FOR DETERMINING ATTENUATION ACROSS OPTICAL FIBER SPLICE A method and apparatus is disclosed for calculating attenuation across an optical fiber splice between a first and second fiber. The method requires that a predetermined constant be calculated from a sample optical fiber. An attenuation algorithm compensates for differences in the numerical aperture of the sample optical fiber and the fibers being spliced. The algorithm further compensates for differences in intensity profiles in the first optical fiber when light is launched into a side thereof, as compared to a intensity profile generated by end light launching as is generally used in telecommunication data transmissions.
