Fiber optic cable splice attenuation per kilometer

Home / Fiber optic cable splice attenuation per kilometer

Calculate optical fiber transmission losses including attenuation, splice loss, connector loss, and total link budget. Fiber attenuation is the reduction in optical power as light travels through the fiber. For multimode fiber, the loss is about 3 dB per km for 850 nm sources, 1 dB per km for 1300 nm. In this case, one would want to take a worst case approach to assure that there is adequate.
