What is the Zero-dispersion wavelength?
Dispersion is defined as the spreading of light pulse when they travel a fiber. This phenomenon is due to the fact that speed of light depends on its wavelength and propagation mode.

it can be defined as
the zero-dispersion wavelength is the wavelength or wavelengths at which material dispersion and waveguide dispersion cancel one another. In all silica-based optical fibers, minimum material dispersion occurs naturally at a wavelength of approximately 1300 nm.
