Abstract : Fiber splice losses and the effect of splices upon the overall loss of built up connections have received considerable attention in the literature from both a theoretical and experimental viewpoint. The methods for determining system bandwidth from measurements on individual fiber lengths, and the effect of splices upon system bandwidth, on the other hand, still is a subject of much debate. In this paper, several different approaches found in the literature are reviewed, some results from bandwidth measurements made at 850 nm on built-up system lengths of telecommunications grade, multimode, graded-index fibers using both time domain and frequency domain measurement techniques are presented and the effect of fusion splices upon bandwidth is examined. The accuracy of the often-used approximate method of bandwidth determination from pulse broadening measurements assuming a Gaussian shaped fiber transfer function also is evaluated. (Author)
