For underground service drops, which cable description best fits the required between the tap and ground block?

• A. Non messenger flooded coaxial drop cable
• B. Messengered coaxial drop cable
• C. Fiber optic cable
• D. Twisted pair cable

Answer: (A)

Underground service drops must be designed for burial, with no need for a supporting messenger, and they need moisture protection for the portion that runs underground. The best description fits a coaxial drop cable that has no messenger and is flooded with moisture-blocking material to resist groundwater. This combination is specifically intended for the underground segment between the tap and the ground block, ensuring reliability in moist environments. Using a messengered coaxial drop would imply an aerial installation where a separate support wire carries the weight, which isn’t the case underground. Fiber optic cable isn’t typically described as the standard underground service drop between the tap and ground block in this context, since the traditional service drop here is coaxial. Twisted pair isn’t used for cable TV service drops.
