Abstract

An empirically based relationship, which is simple yet highly correlated, has been found to exist between optical 3dB bandwidth and impulse response RMS pulse width in multimode graded index optical fibers. Experimentation has shown this relationship to be independent of the degree of externally induced mode coupling. Propagation of error analysis was used to find the total ±3cσ limits, and theoretical comparisons are made for three ideal pulse shapes - cosine, raised cosine and gaussian.
