For long distances, especially those covering more than 2 km, Single Mode Fiber (SMF) is the appropriate choice because it allows light to travel straight down the fiber without much reflection, enabling data transmission over long distances without significant signal loss. Multimode Fiber (MMF) is generally suited for shorter distances due to modal dispersion, which can lead to signal loss and degradation over long distances. Cat 6 and Cat 6a are both types of copper cables which are typically limited to 100 meters in Ethernet applications; thus, they are unsuitable for a distance of 10 km.
