Question
Which effects make it necessary to limit the total cable length per line segment to 1000 m?
Answer
A — Signal damping and edge-rounding by the cable capacity, plus a signal-level drop from the resistive load
Correct: These two effects degrade the signal, so the segment is limited to 1000 m.
