Category 7 cable (Cat 7), (ISO/IEC 11801:2002 category 7/class F), is a cable standard for Ethernet and other interconnect technologies that can be made to be backwards compatible with traditional Cat 5 and Cat 6 Ethernet cable. Cat 7 features even more strict specifications for crosstalk and system noise than Cat 6. To achieve this, shielding has been added for individual wire pairs and the cable as a whole.

The Cat 7 cable standard has been created to allow 10 Gigabit Ethernet over 100 m of copper cabling (also, 10-Gbit/s Ethernet now is typically run on Cat 6a). The cable contains four twisted copper wire pairs, just like the earlier standards. Cat 7 can be terminated either with 8P8C compatible GG45 electrical connectors which incorporate the 8P8C standard or with TERA connectors. When combined with GG45 or TERA connectors, Cat 7 cable is rated for transmission frequencies of up to 600 MHz.

Category 7a (or Augmented Category 7) operates at frequencies up to 1000 MHz, suitable for multiple applications in a single cable including 40 Gigabit Ethernet, 100 Gigabit Ethernet, and CATV (862 MHz). Simulation results have shown that 40 Gigabit Ethernet is possible at 50 meters and 100 Gigabit Ethernet is possible at 15 meters. Mohsen Kavehrad and researchers at Pennsylvania State University believe that either 32 nm or 22 nm circuits will allow for 100 Gigabit Ethernet at 100 meters.

Advantages of CAT7
• Performance to 10 GB/s and beyond, far exceeding all performance requirements for 10GBASE-T.
• Bandwidth of 1.2 GHz per pair, twice the category 7/class F specifications and the highest of any available copper system.
• Validated for TEMPEST high-security government applications.
• Cable sharing - Shielded design and 1-, 2- and 4-pair outlet and plug modularity allow the simultaneous support of multiple applications over a single cable, administered in a single outlet.
• Future-proof performance and flexibility make TERA ideal for data centers, healthcare imaging and financial applications.


Category 6E cables also exceed TIA/EIA-568-B.2-1 Category 6 and ISO/IEC 11801 Class E performance requirements by substantial margins on all parameters. The AMP NETCONNECT Category 6 System complies with all of the performance requirements for current and proposed applications such as Gigabit Ethernet (1000BASE-Tx), 10 and 100BASE-Tx, token ring, 155 Mbps ATM, 100 Mbps TP-PMD, ISDN, analog and digital video, and analog and digital voice (VoIP).
