How do you determine which cabling type to use in a network?

To determine which cabling type to use in a network, consider factors such as the required bandwidth, distance, and environmental conditions. For high-speed data transmission over long distances, fiber optic cables are ideal, while twisted pair cables (like Cat 6 or Cat 6a) are suitable for shorter distances and moderate bandwidth needs. Additionally, assess the installation environment to choose between shielded or unshielded cables based on interference potential. Finally, budget constraints and future scalability should also influence the decision.
