Dark fiber refers to unused, unlit or unactivated fiber optic cabling laid underground, underwater, or suspended above ground that has been deployed with the intention of creating a network infrastructure. The fibers themselves are made of glass or plastic and are capable of transmitting data at very high speeds over long distances using light. The term "dark" is used to indicate that the fiber is currently inactive and is not transmitting any data. The potential bandwidth of these unused fibers is significant, and they have the potential to support high-speed data communication over long distances. Dark fiber is often leased or sold to telecom companies or internet service providers, who can use the fibers to build their own network infrastructure, expand their existing networks, or provide high-speed connectivity to their business customers. It can also be used by universities or research institutions for data-intensive research or by government agencies for secure communication.(Created using ChatAI)
