Temperature Dependence of Chromatic Dispersion in Various Types of Optical Fibers

摘要

We have measured temperature dependence of chromatic dispersion for various types of optical fibers. Its coefficient depends strongly on the dispersion slope. Dispersion flattened fiber has a fairly low coefficient of -0.0005 ps/nm/km/°C compared with -0.0038 ps/nm/km/°C for large core fiber. Transmission lines with low dispersion slope consisting of pure silica core fiber and dispersion compensating fiber also exhibit low coefficients less than -0.001 ps/nm/km/°C because of their compensating effects.
