[pdf] For IP surveillance, shielded Cat5e or Cat6 cables with proper twist and shielding configurations can reliably transmit digital video over long distances when combined with PoE (Power over Ethernet) technology. Fiber optic transmission distance varies based on fiber type, environmental conditions, and equipment selection. This guide covers fiber distance limitations, influencing factors, application-based selection, and technologies that extend optical. 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. Attenuation is the progressive loss of signal strength that occurs as light travels through the fiber. The greater the distance, the greater.
