What technology combines fiber-optic and coaxial cable in broadband systems?

The technology that combines fiber-optic and coaxial cable in broadband systems is known as HFC, which stands for Hybrid Fiber-Coaxial. This architecture effectively utilizes the advantages of both fiber-optic and coaxial cables. Fiber-optic cables are used for the main distribution network, offering high bandwidth and long-distance transmission capabilities, while coaxial cables are employed for the last mile, connecting individual homes and businesses to the network. This combination allows service providers to deliver high-speed internet, television, and phone services efficiently.

In contrast, other technologies like DSL (Digital Subscriber Line) rely solely on traditional copper telephone lines for internet access, while WLAN (Wireless Local Area Network) focuses on wireless communication and does not directly use either fiber-optic or coaxial technologies. Ethernet is primarily a local area networking technology that typically utilizes twisted pair cables but does not specifically leverage the hybrid model inherent in HFC setups. HFC remains a significant architecture in providing comprehensive broadband services due to its ability to deliver high data rates over considerable distances.
