Longer wavelengths of light exhibit less. scattering than shorter wavelengths. For example, light at 1550nm loses 0.2 to 0.3 dB per. kilometer (dB/Km) of fiber length due to Rayleigh scattering, whereas light at 850nm loses. 4.0 to 6.0 dB/Km from scattering. A higher density of dopants in a fiber will also create more. scattering and thus higher levels of attenuation per kilometer.
