Which of the following cable types would be the BEST option to transmit video 2000 feet (609.6 meters) without the use of a repeater?
The correct answer is B. Fiber. Fiber optic cable can transmit signals over distances far exceeding 2000 feet without a repeater because it uses light rather than electrical signals, which suffer from significant attenuation over long runs. All listed copper and coaxial cable types degrade well before that…

Why each option
Fiber optic cable can transmit signals over distances far exceeding 2000 feet without a repeater because it uses light rather than electrical signals, which suffer from significant attenuation over long runs. All listed copper and coaxial cable types degrade well before that distance.
RG-59 is a thin coaxial cable rated for shorter runs and experiences significant signal attenuation well before 2000 feet, making it unsuitable for this distance without a repeater.
Fiber optic cable transmits data as pulses of light through a glass or plastic core, experiencing minimal signal attenuation over distance compared to copper-based cables. Single-mode fiber can carry signals tens of kilometers without a repeater, making it the only viable option among those listed for a 2000-foot (609.6-meter) video transmission run without signal amplification.
CAT6 twisted-pair cable has a maximum recommended segment length of 328 feet (100 meters) for Ethernet, far shorter than 2000 feet.
RG-6 coaxial cable supports longer runs than RG-59 but still experiences attenuation that makes reliable transmission at 2000 feet without a repeater impractical for video signals.
