RCDD · Question #184
The following diagram indicates what type of CATV distribution system?
The correct answer is A. Trunk and tap. The trunk and tap distribution system uses a main coaxial trunk cable with directional tap devices installed at intervals to branch signals to individual outlets. This is one of the most common traditional CATV distribution architectures.

Why each option
The trunk and tap distribution system uses a main coaxial trunk cable with directional tap devices installed at intervals to branch signals to individual outlets. This is one of the most common traditional CATV distribution architectures.
A trunk and tap system routes the main signal along a central coaxial trunk cable, with passive or active tap devices placed along that trunk at defined intervals to extract a portion of the signal for distribution to subscriber drops. The diagram would show this characteristic branching pattern off a common trunk, which distinguishes it from home run or fiber architectures. Amplifiers are typically placed along the trunk to compensate for signal loss over distance.
Video over balanced twisted-pair uses structured Category cabling with balun converters rather than a coaxial trunk-and-tap arrangement.
Video over optical fiber uses fiber optic cable as the distribution medium with optical nodes converting signals, which appears architecturally different from a coaxial trunk layout.
Home run topology shows individual dedicated coaxial runs from each outlet back to a central headend or TR, rather than a shared trunk with branching taps.
