Which statement best matches common network cabling types to typical speeds?

• A. UTP Cat5e up to 1 Gbps; Cat6 up to 10 Gbps short distances; fiber supports 10 Gbps+ with high distances; fiber types multimode and single-mode.
• B. UTP Cat5e supports 10 Gbps; Cat6 supports 40 Gbps.
• C. UTP Cat5e is fiber optic; Cat6 is copper; multimode fiber cannot be used for 10 Gbps.
• D. Fiber is never used for high-speed LAN; UTP Cat6 is best for long distances.

Answer: (A)

Understanding how common network cabling types map to speeds and distances helps you pick the right link for a given site. Copper twisted-pair cables vary by category. Cat5e can carry up to about 1 Gbps over the standard 100-meter Ethernet link. Cat6 can handle 10 Gbps, but on copper that speed is limited to shorter runs before performance degrades, so you typically see 10 Gbps on Cat6 only over shorter distances; Cat6A then extends the 10 Gbps capability to the full 100 meters. Fiber optics deliver much higher speeds and longer distances. Multimode fiber is used for shorter, inside-building links, while single-mode fiber handles very long distances; both types can support 10 Gbps and higher with the right transceivers and equipment.

So the statement matches typical expectations: copper Cat5e up to 1 Gbps, copper Cat6 up to 10 Gbps on shorter runs, and fiber capable of 10 Gbps and beyond over longer distances with both multimode and single-mode fibers. Other options mix up these facts, such as claiming Cat5e can do 10 Gbps or that fiber isn’t used for high-speed LAN.
