Paper Abstract

A new technique for the multimode fiber bandwidth prediction based on a preform profile is suggested. It allows to calculate the output pulse distortion and the bandwidth of a fiber to be drawn dependently of the excitation conditions under which it will operate. It is shown that the accuracy of the bandwidth prediction for 1.5-2.5 km fibers is about 10 %, the bandwidth being 1..1.5 GHzxkm. To achieve this accuracy it is necessary that the excitation conditions and differential mode attenuation be exactly reproduced in the calculation. And the profile variations along length should not be considerable. The predic-tion technique was adapted to P101 Preform Analyser (York Technology) and can replace alpha-approximation curve-fitting during routine manufacture of multimode preforms.
