Cat 5 vs. Cat 7A
Comparing 2 standards across 14 specifications. 14 key differences identified.
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.
Category 7a (Cat 7a, Augmented) is an ISO/IEC 11801 Class F_A standard ratified in 2010. Operating up to 1000 MHz (and tested up to 1200 MHz), it utilizes mandatory S/FTP shielding and specialized connectors (TERA/GG45/ARJ45), supporting 10 Gbps at 100 meters and broadband CATV distribution.
