DOCSIS enables data transmission over which medium?

• A. Coaxial cable
• B. Fiber optic
• C. Wireless
• D. Satellite

Answer: (A)

DOCSIS enables data transmission over coaxial cable. It’s the standard used by cable TV providers to carry broadband by putting data onto RF channels on the coax that runs into the home. In many networks, fiber runs from the headend to a distribution node (hybrid fiber-coax), and coax from the node to the customer delivers the actual data to a cable modem. While fiber, wireless, or satellite are other delivery methods, DOCSIS itself governs how data travels over the coaxial medium in the cable system.
