Fiber bandwidth measurement using pulse spectrum analysis

Abstract

The pulse spectrum analysis (PSA) method of measuring fiber bandwidth has been suggested as an alternative to the frequency and time domain methods, but there is a paucity of information on the technique and very little data. In fact, we know of no measurement comparisons between the PSA method and the frequency and time domain methods. The PSA method has the advantage of being very simple and gives results that are consistent with the time domain and frequency domain methods. The International Electrotechnical Commission (IEC) recommends the PSA method, but the Electronics Industries Association (EIA) of the U.S.A. takes no position in this regard. This paper gives results of an experiment which compared the three methods.
