Which type of fiber should a technology company use for connections over a distance of 2 kilometers for high-speed data transfer?

Single Mode Fiber (SMF) is the recommended choice for high-speed data transfer over distances of 2 kilometers. This type of fiber has a smaller core diameter, typically around 8 to 10 micrometers, which allows it to transmit light directly down the fiber with minimal interference from modal dispersion. As a result, SMF can maintain a higher bandwidth over longer distances compared to other types of fiber optics.

Over a distance of 2 kilometers, the performance advantages of Single Mode Fiber become even clearer, as it is designed to transmit signals over much longer distances without significant loss or degradation. This makes it ideal for applications that require a reliable connection for high-speed data transfer, such as telecommunications and data centers.

In contrast, Multimode Fiber (MMF) is generally better suited for shorter distances, typically up to about 300-400 meters for high-speed applications, due to issues such as modal dispersion that can affect performance at longer distances. Plastic Optical Fiber (POF) is more commonly used in consumer applications and short-distance networks but lacks the bandwidth and distance capabilities of SMF. Standard Copper Cable, while useful for various applications, has limitations in terms of distance and data transfer rates compared to fiber optics. Therefore, for a technology
