What standard do broadband cable operators use to provide high-speed data connections via HFC networks?

Broadband cable operators use DOCSIS (Data Over Cable Service Interface Specification) as the standard to provide high-speed data connections through Hybrid Fiber-Coaxial (HFC) networks. DOCSIS is essential because it enables the transmission of data over cable television infrastructure, allowing operators to efficiently deliver internet services alongside traditional cable services.

This standard supports various levels of data transmission speeds and ensures compatibility between different network equipment. Its significance lies in its ability to utilize existing cable television networks, making it a highly effective solution for high-speed internet access without the need for extensive new infrastructure.

In contrast, the other options represent different technologies or standards used for other types of data delivery. DSL is specifically designed for telephone lines and does not apply to coaxial cable networks. IPTV refers to streaming television services delivered over the internet and does not pertain directly to broadband connectivity standards. Ethernet is a networking technology commonly used in local area networks (LANs) but is not specific to cable operators providing broadband internet via HFC networks.
