Hybrid fiber coax (HFC) networks combine fiber optics and coaxial cables to create a multiple system operator (MSO) for cable television and high- or very-high-speed internet. The fiber ends near or at residential and commercial buildings, and it is extended up to the subscriber’s unit using coaxial cables. With this type of architecture, we can reuse former television distribution networks in order to offer interactive, digital services.
HFC networks, which can provide service to millions of users, broadcast analog television programs, frequency-modulated (FM) radio broadcasts, and interactive applications (on-demand or subscription digital television, public telephony, internet access, etc.). Theoretically, these types of networks could provide users with service speeds of up to 10 GB/s.
