What type of cable should be used for an underground service drop between the tap and the ground block?

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

Answer: (A)

Underground service drops must be rated for burial and moisture resistance. A non messenger flooded coaxial drop cable fits that need because it is gel-filled to prevent water intrusion and doesn’t require a separate supporting messenger wire, making it suitable for a direct underground run from the tap to the ground block. Messengered coaxial is intended for aerial routes where extra support is needed, not for underground burial. Fiber optic drop cable is used for fiber deployments, not coax. Twisted pair drop cable is for copper telephony or data, not coaxial service drops. So the best fit is the non messenger flooded coaxial drop cable.
