Abstract:

An apparatus and method for measuring dispersion in an optical fiber including transmitting light of a first wavelength and a second wavelength through the optical fiber, measuring the difference in time required for light of the first wavelength and light of the second wavelength to traverse the fiber, and calculating the dispersion of the fiber from the two wavelengths and the time difference. Lasers may be used as light sources and an oscilloscope may be used to measure the time difference.
