The length dependence of pulse spreading in the CGW-Bell-10 optical fiber

Abstract

Previous measurements of pulse broadening in the CGW-Bell-10 optical fiber showed very low dispersion ( < 2 ns/km). We recently measured pulse spreading as a function of length in this fiber. The data indicate a (length) <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1/2</sup> dependence, at wavelengths of 0.6328, 0.9, and 1.06 µm, for long fiber lengths (> 550 m) which are of practical significance.
