A: For most applications, the maximum distance of a single-mode cable is around 160 kilometers. Q: How far can multimode fiber go? A: It varies with the data speed and fiber type. Fiber optic cable can be run anywhere from 300 meters up to 80 kilometers (roughly 50 miles) depending on the cable type, transceiver used, and network standard. 5 dB per kilometer at 1550nm, light absorption and scattering still accumulate over long spans. Range tells you how much ground you can cover before needing tools like optic cable extender devices or extra cables.
