A network engineer is tasked with setting up a long-distance fiber optic link between two data centers located 120 kilometers apart. Which type of fiber optic cable should the engineer use to ensure efficient and reliable data transmission over this distance?
Single-mode fiber is designed for long-distance data transmission, capable of carrying signals over 100 kilometers without the need for signal repeaters due to its ability to limit light mode dispersion. This makes it the appropriate choice for distances like 120 kilometers between two data centers. Multimode fiber, on the other hand, is typically used for shorter distances up to 2 kilometers due to modal dispersion, which can lead to signal loss over longer distances.
