What is the minimum separation distance for aerial communication cables?

• A. 25 feet
• B. 10 feet
• C. 50 feet
• D. 75 feet

Answer: (A)

This question is about maintaining safe clearance for overhead communications lines. The standard minimum separation is set to give a buffer for line sag, wind, and weather effects so the aerial cables don’t come into contact with other wires or structure components and to keep maintenance crews safe. Twenty-five feet provides enough room for the cable to sway or sag without approaching power lines or nearby hazards, while still being practical for routing and installation. A smaller distance like ten feet would leave insufficient room for movement and could lead to accidental contact; larger gaps such as fifty or seventy-five feet are typically unnecessary for most aerial telecom cables and would complicate routing and installation.
