Comparing:
Cat 5e
Cat 7A
Category 5e (Cat 5e, Enhanced) is an Ethernet twisted-pair copper cable standard defined in TIA/EIA-568-B.2. Rated for frequencies up to 100 MHz, it introduced stringent electrical crosstalk specifications, enabling reliable 1000BASE-T (1 Gbps Gigabit Ethernet) transmission up to 100 meters across all four 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.
