A fiber optic backbone is a link between two locations on the same network that uses fiber optic cable to transmit data. Fiber optic backbones are commonly used to connect different parts of large facilities like offices, schools, and hospitals. They provide more bandwidth than copper cables and can transmit data over greater distances without signal loss or interference. As data needs continue increasing, fiber optic backbones allow networks to scale their bandwidth capacity and provide future-proof connectivity within buildings.
