Fiber optic cable is recognized as the preferred choice for high-speed data transmission in networks due to its ability to carry data over long distances with minimal signal loss and interference. Fiber optic cables use light to transmit data, which allows for extremely high bandwidths and faster speeds compared to traditional copper cables. This technology is particularly advantageous in environments where high-speed internet access is required, such as data centers, enterprise networks, and expanding infrastructure for broadband services.

On the other hand, while coaxial cables and twisted pair cables (including various forms of Ethernet cables) are still widely used for networking, they generally cannot match the performance capabilities of fiber optic cables. Coaxial cables are often limited in bandwidth and distance compared to fiber optics, and twisted pair cables, while effective for networking up to certain speeds (like those used in standard Ethernet setups), still fall short of the high-speed data rates achievable with fiber optics.
