HybridFiberCoaxNetz

HybridFiberCoaxNetz, often abbreviated as HFC, refers to a telecommunications network architecture that combines fiber optic and coaxial cable technologies. This hybrid approach is widely used for delivering broadband internet, cable television, and telephone services to homes and businesses. The core principle of HFC is to leverage the high bandwidth and low signal degradation of fiber optic cables for the majority of the network's distance, connecting the service provider's central office to a local node. From this node, coaxial cable is then utilized to connect individual subscriber premises. This design offers a cost-effective solution as it can often utilize existing coaxial cable infrastructure, reducing the need for complete overhauling. Fiber optic cables provide the high-speed data backbone, ensuring efficient transmission over long distances, while coaxial cables handle the "last mile" connection, which is typically shorter and more readily accessible for deployment. The transition from fiber to coaxial typically occurs at a neighborhood node, where optical signals are converted into radio frequency (RF) signals suitable for transmission over coaxial cable. This architecture has become a dominant force in broadband deployment due to its balance of performance and economic feasibility.
