The maximum distance of copper is around 328 feet (100 meters), which is a far shorter range than is offered by either of the fiber optic cable types. This is because fiber optic cable is not affected by attenuation, dispersion, or EMI in the same way that copper is. Many factors decide the fiber cable distance, but the key factors include the below six aspects. Attenuation First is the attenuation of the optical fiber. For some. Fiber optic cable transmission distance is determined by two primary physical factors that affect signal quality as light travels through the fiber medium. The selection of fiber optic cables over copper wires or vice versa depends on factors such as bandwidth, distance, and cost of transmission.
