Side-by-Side Comparison Ethernet Cables

Cat 5 vs. Cat 6

Comparing 2 standards across 14 specifications. 13 key differences identified.

Comparing:
Cat 5
Cat 6

Category 5 (Cat 5) is a legacy twisted-pair copper cable standard defined in ANSI/TIA/EIA-568-A. Rated for frequencies up to 100 MHz, it was the foundational medium for 100BASE-TX Fast Ethernet (100 Mbps) over distances up to 100 meters, utilizing two of its four twisted pairs.
