Organizing and summarizing search results for youFiber attenuation (loss of signal strength) in optical fibers is wavelength dependent. Here are some key points:- Attenuation is usually expressed in dB/km at a specific wavelength.
- Single-mode fibers have lower attenuation than multimode fibers.
- The higher the wavelength, the lower the attenuation.
- The three main wavelengths used for fiber optic transmission are 850, 1300, and 1550 nanometers.
