What category is recommended for new data cable installations?

• A. Category 5e
• B. Category 6 or higher
• C. Category 3
• D. Category 7

Answer: (B)

For new data cable installations, you want at least Category 6. This choice future-proofs the run and supports current and upcoming network speeds, reducing interference and crosstalk. Category 5e was common for older setups but is limited to around 1 Gbps and becomes outdated for new builds. Category 3 is an older voice-telephony standard and isn’t suitable for data. Category 7 is capable but less common in typical installs due to specialized connectors and standards, making Cat6 (or higher) the practical default. Cat6 or higher ensures compatibility with modern Ethernet standards (including 10GBASE-T on appropriate lengths) and aligns with current cabling standards.
