Home / What is the normal level of multimode optical attenuation in fiber optic cables
For multimode fiber, the loss is about 3 dB per km for 850 nm sources, 1 dB per km for 1300 nm. This Applications Engineering Note (AE Note) discusses the criteria for properly selecting the optimal multimode fiber (MMF) for enterprise applications. The document gives details on the measurement procedure, which is based on the Electronics Industries Association Recommended Standard as published in RS. Attenuation in fiber optics is the gradual loss of light signal strength as it travels through a fiber cable.
Although attenuation is significantly lower for optical fiber than for other media, it still occurs in both multimode and single-mode transmission. An efficient optical data link must have enough light
