Cat7 is a fully shielded copper cable standard rated for 10 Gbps at 100 meters and frequencies up to 600 MHz. It uses individually shielded pairs (S/FTP construction) to provide superior crosstalk isolation. However, Cat7 is rarely specified in U.S. commercial installations because ANSI/TIA has not ratified it as a recognized standard — TIA-568 stops at Cat6A for copper horizontal cabling.
Cat7 is recognized under the ISO/IEC 11801 international standard and sees more adoption in European markets. In practice, most U.S.-based cabling engineers — including Just Cabling — specify Cat6A rather than Cat7 for high-performance copper runs, since Cat6A provides equivalent 10G performance within the TIA framework, uses standard RJ45 connectors, and is less expensive.
If your project spec calls for Cat7 under an ISO/IEC 11801-based design standard, Just Cabling can accommodate that requirement. For most DFW commercial projects, Cat6A is the more practical and cost-effective path to 10G copper.
