  • Gigabit fiber optic cable transmission distance

    Gigabit fiber optic cable transmission distance

    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. Fiber optic cable transmission distance is determined by two primary physical factors that affect signal quality as light travels through the fiber medium. Attenuation First is the attenuation of the optical fiber. For most enterprise or data center applications using multimode fiber, the practical limit sits between 300 m and 550 m. It operates at a 1310nm wavelength and is widely used in enterprise, campus, and access networks where copper cabling or short-reach multimode optics are no.
