  • Broadband fiber optic cable transmission length

    Broadband fiber optic cable transmission length

    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. For most enterprise or data center applications using multimode fiber, the practical limit sits between 300 m and 550 m. Multimode fiber typically operates at 850nm and 1300nm, supporting short-distance communication due to higher attenuation and modal dispersion.
