Cat Ethernet Cables

Choose based on required network speed, distance, and interference environment: Cat5e supports up to 1 Gbps for typical home use; Cat6 and Cat6a support 1–10 Gbps with better performance and longer 10 Gbps reach for Cat6a; Cat7 and Cat8 provide higher bandwidth and shielding for data centers or very high-speed short runs. Match cable category to your router/NIC capabilities and future-proofing needs

Most consumer networks use RJ45 connectors and solid or stranded conductors; choose stranded for frequent flexing and patch cables, solid for permanent wall runs. Measure the run including slack; avoid excess coiling that can degrade signal—order the next standard length up if you need slack for routing

Shielding helps reduce electromagnetic interference in environments with many electrical cables or noisy equipment; unshielded twisted pair (UTP) is typically sufficient for most homes. If using shielded cables, ensure both ends and connected hardware support grounding to get the benefit

Prices vary by category, length, shielding, and build quality; budget options commonly fall under $50 for shorter runs, while higher-category, long, or heavy-shielded cables can cost more. Brand, packaging (bulk vs. retail), and additional features like snagless boots or gold-plated contacts also influence cost

Round cables are more common for in-wall or conduit runs because they better preserve twist integrity and shielding; flat cables can be useful for tight spaces, under carpets, or for cosmetic surface routing but may have reduced performance at longer lengths. Choose based on installation constraints and required performance

Use a network cable tester to verify continuity, pair wiring, and performance; check link speed on connected devices to confirm expected throughput. Avoid sharp bends, kinks, and excessive tension, keep connectors clean and dry, and replace damaged cables to maintain reliable performance

Yes, you can mix categories; the network link will operate at the lowest common category and device capability on that segment. For best performance, use consistent higher-category cabling for backbone runs and upgrade endpoints to take full advantage of higher speeds
