Single-mode fiber is the optimal choice for long-distance and high-bandwidth applications as it uses laser light to send signals, which allows for smaller modal dispersion over long distances compared to multimode fiber and other types of cables. This makes it ideal for large-scale data centers that require high-speed data transfer across long distances without susceptibility to electrical interference. Multimode fiber, while also resistant to electrical interference and useful for moderate distances, cannot maintain signal quality over as long distances as single-mode. Coaxial and Twinaxial cables are susceptible to electromagnetic interference and are generally used for shorter distances.
