Category 7 cable (Cat7), (ISO/IEC 11801:2002 category 7/class F), is a cable standard for Ethernet and other interconnect technologies. CAT 7 is backwards compatible with traditional Cat5 and Cat6 Ethernet. Cat7 features even more strict specifications for crosstalk and system noise than Cat6. Shielding has been added for individual wire pairs on the Category 7 cable.

Cat7 has been designed as a standard for Gigabit Ethernet over 100m of copper cabling The cable contains four twisted copper wire pairs, just like the earlier standards. Cat7 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, Cat7 cable is rated for transmission frequencies of up to 600 MHz. Xmultiple's UltraJAX connectors are designed specifically for these high speeds with not contact pins and a printed circuit board with contact pads integrated into the RJ45 style housing.

CAT7a For Frequencies up to 1000MHz

Category 7a which is also commonly referred to as Augmented Category 7, operates at frequencies up to 1000 MHz. CAT7a is designed for multiple applications in a single cable including 40 Gigabit Ethernet, 100 Gigabit Ethernet, and CATV (862 MHz).[1][2][3). Test results have shown 40 Gigabit Ethernet will work up to 50 meters and 100 Gigabit Ethernet is possible up to 15 meters. Small form factor pluggable products are available by Xmultiple in both copper and fiber optics for the 40GB and 100 GB applications.
