A network technician is tasked with setting up a network in a large data center. Given the need for high speed data transfer and distances that exceed 100 meters between devices, which type of cable should the technician use?
Single-mode fiber is the most suitable choice for this scenario because it provides a higher transmission rate and can cover long distances (beyond 100 meters) without signal degradation. Multimode fiber also supports high data rates but is typically used for shorter distances, such as connecting multiple adjacent racks in a datacenter. CAT5e and CAT6 cables are not feasible for lengths exceeding 100 meters as signal quality can degrade, especially at high data rates.
