4 Overview
Fiber dispersion is one of the characteristics of optical fiber transmission, the group is due to the different wavelengths of light and different modes of propagation in the fiber
At different speeds and delays caused by the difference of the optical signal. Single-mode fiber is mainly material dispersion and waveguide dispersion, material dispersion
And waveguide dispersion of the combined effect is called chromatic dispersion (hereinafter referred to as dispersion).
Fiber dispersion tester is used to measure the fiber dispersion tool for measuring the zero-dispersion wavelength of the optical fiber, the zero-dispersion
Wavelength slope. Methods of measurement for the phase shift method. Principle is shown in Figure 1.
