Method and apparatus for determining attenuation across optical fiber splice.

摘要

A method and apparatus for determining optical power attenuation across a splice between first and second optical fibers utilizes the algorithm:where Ltel is determined by compensating for differences in intensity profiles existant in the first optical fiber when injecting light therein for purposes of measuring attenuation versus the intensity profile created when injecting light into the first fiber for transmitting telecommunications data and the light has been propagating in the fiber for a distance and steady state intensity distribution is achieved. Preferably, a numerical aperture of the first optical fiber and a sample optical fiber are empirically determined, and Ltel is calculated by compensating for differences between these numerical apertures.
