Non-zero dispersion-shifted fiber (NZ-DSF) is a type of optical fiber designed to manage the effects of chromatic dispersion, which can negatively impact the performance of high-speed fiber optic communication systems. This type of fiber is specifically engineered to have a non-zero amount of chromatic dispersion at the wavelengths used for light transmission, typically around 1550 nm, which is a standard for long-haul fiber optic communications.
