A data center requires a high-speed network with no electromagnetic interference for connections within the same building. Which cable type should be used?

CAT 5e cables are twisted pair cables that support high-speed Ethernet but are susceptible to electromagnetic interference. Although they can handle gigabit speeds over short distances, they do not provide the same level of performance and signal integrity as multimode fiber in environments with potential interference.

Wireless connections can offer flexibility and convenience but are prone to interference from physical obstructions and electromagnetic sources. In a data center where reliability and speed are crucial, wireless technologies can introduce latency and inconsistent performance, making them less suitable for high-speed, critical connections.

Coaxial cables are capable of transmitting data at relatively high speeds and are often used for cable television and internet services. However, they are not optimized for the high-speed and low-interference requirements of a data center, where multimode fiber excels due to its superior bandwidth capabilities and reduced signal loss over distance.
