Factors limiting fiber optic communication distance
5 dB per kilometer at 1550nm, light absorption and scattering still accumulate over long spans. Many factors decide the fiber cable distance, but the key factors include the below six aspects. This guide explores the key factors affecting fiber optic transmission distance and provides practical selection guidelines for a stable and cost-effective network deployment. Attenuation is the progressive loss of signal strength that occurs as light travels through the fiber. Chromatic dispersion, modal dispersion, mechanical stress, bending losses, connectivity issues, and other environmental factors further curtail distance.
