Which cable arrangement is typically used in a loop-through system?

In a loop-through system, the primary design allows for the continuous flow of signal by enabling cables to connect in a manner that supports signal distribution to additional locations. The correct answer involves an output port cable going to another section of the house, which aligns perfectly with how loop-through systems function.

In this configuration, the input from the source device can be fed into one outlet. Then, rather than terminating at that outlet, the signal can be sent onward to additional areas or devices by utilizing the output port of the outlet. This arrangement is particularly useful for extending network coverage or connecting multiple devices without the need for additional signal sources.

The other options do not follow the typical characteristics of a loop-through arrangement. The arrangement described by the first choice fails to illustrate a continuity of signal beyond the immediate outlet. Connecting the input cable to the output port of a splitter is also not representative of a loop-through system, as it implies a branching out rather than a continuous run. Finally, running a cable directly to the wall doesn't maintain the necessary path for signal distribution as typical of loop-through arrangements.
