Single-mode fiber is best suited for long-distance, high-speed transmissions due to its ability to transmit data over extensive distances without significant signal degradation, typically up to 90 kilometers without the need for a repeater. Multimode fiber, while also used for high-speed transmissions, is generally suitable for shorter distances, typically up to 550 meters for 10 Gbps. Coaxial cable and Direct attach copper cables have lower transmission distance capabilities and are not ideal for data center interconnections that involve long distances.
