Copper Cabling - N10-008 CompTIA Network+ : 1.3
Professor Messerγ»7 minutes read
Copper cabling is necessary for Ethernet networks in different categories like 5e, 6, 6A, and 7, supporting various data transmission speeds and distances. Coaxial cables are used for cable modem and TV connections, while twinax cables are for short-distance 10 gig Ethernet connections.
Insights
- Different categories of Ethernet cables are designed for specific network speeds and distances, with Category 5e suitable for 1000BASE-T, Category 6 for 10GBASE-T, and Category 6A, 7, and 8 supporting higher speeds over varying distances.
- Coaxial cables, such as RG-6, are utilized for cable modems and television connections, while twinax cables are ideal for short-distance 10 gig Ethernet applications due to their 5-meter limit.
