RCDD · Question #186

The following diagram represents what type of CATV distribution system?

The correct answer is A. Home run. A home run distribution system provides a dedicated, individual coaxial cable from a central source directly to each outlet with no shared trunk or taps.

Why each option

A home run distribution system provides a dedicated, individual coaxial cable from a central source directly to each outlet with no shared trunk or taps.

AHome runCorrect

In a home run architecture, every CATV outlet is connected by its own separate cable running directly back to the central distribution point or headend. This design eliminates shared signal paths between outlets, maximizing signal integrity per port. The diagram showing multiple individual runs from a single origin point is the defining characteristic of a home run system.

BTrunk and tap

A trunk and tap system uses a single main trunk cable with directional couplers or taps branching off to serve multiple outlets, which would show a branching topology, not individual parallel runs.

CVideo over balanced twisted-pair

Video over balanced twisted-pair distributes video using UTP or STP cabling with baluns, which involves a fundamentally different cable medium than coaxial.

DVideo over optical fiber

Video over optical fiber uses fiber optic cable and requires optical transmitters and receivers, representing a different physical layer than shown in a coaxial home run diagram.
