Alexandra is reading an article about SMF and MMF cables. What conclusion can she draw from her findings?

MMF provides over medium distances. MMF is most often used within a area of one building, while SMF can be used between buildings.

Single-mode fibers (SMF) are primarily used for long-distance communication due to their ability to carry signals over large distances without signal loss. On the other hand, multimode fibers (MMF) are more suitable for shorter distances, often within a building.

For example, SMF can be used for communication between buildings, across cities, or even continents, while MMF is commonly employed for shorter distances like within a single building or campus.

Overall, the choice between SMF and MMF cables depends on the required distance and the level of signal attenuation permissible in the communication network.
