What is the primary distribution technology used by traditional cable systems to deliver video and data to multiple homes?

• A. HFC (Hybrid Fiber-Coaxial) Network
• B. Fiber to the Home
• C. Satellite Distribution
• D. DSL

Answer: (A)

Hybrid Fiber-Coaxial (HFC) networks are the backbone of traditional cable systems. In this setup, optical fiber carries signals from the headend to neighborhood nodes, and from those nodes the signals are distributed over coaxial cable all the way to homes. This mix delivers the high bandwidth needed for many TV channels and data services while keeping costs reasonable, since running coax to every house is cheaper than running fiber all the way to each premises. Fiber to the Home would push fiber all the way to each subscriber, which isn’t how classic cable plants are designed. Satellite and DSL represent different delivery methods or last-mile technologies and aren’t the standard for traditional cable distribution.
