 CAT7 wire with twisted pairs and shielding exposed. Category 7 cable (CAT7), (ISO/IEC 11801:2002 category 7/class F), is a cable standard for Ultra Fast Ethernet and other interconnect technologies that can be made to be backwards compatible with traditional CAT5 and CAT6 Ethernet cable. CAT7 features even more stringent specifications for crosstalk and system noise than CAT6. To achieve this, shielding has been added for individual wire pairs and the cable as a whole.

The CAT7 cable standard has been created to allow 10-gigabit Ethernet over 100 m of copper cabling. The cable contains four twisted copper wire pairs, just like the earlier standards. CAT7 can be terminated in RJ-45 compatible GG45 electrical connectors which incorporate the RJ-45 standard, and a new type of connection to enable a smoother migration to the new standard. When combined with GG-45 connectors, CAT7 cable is rated for transmission frequencies of up to 600 MHz. 10-gigabit Ethernet (XGbE or 10GbE) is the most recent (as of 2005) and fastest of the Ethernet standards. ...

Other categories of network cables - Cat 1 and Cat 2: 1 Mbit/s cables for transferring voice and low-speed data.
- Cat 3: 10 Mbit/s cables, a well-known variant of Cat 5 cables.
- Cat 4: 20 Mbit/s cables, being phased out in favor of Cat 5.
- Cat 5: 100 Mbit/s cables, a very common ethernet cable.
- Cat 6: defined by the ANSI TIA/EIA 568B-2.1. It is suitable for 1000 Base-T Ethernet up to 100 m.
- Cat 7 cable, with four individually-shielded pairs (ScTP) inside an overall shield, has been proposed as a standard but did not gain its popularity. It is designed for transmission frequencies up to 600 MHz, which should enable it to carry 10-Gigabit Ethernet (10GBaseT), but requires a redesigned RJ-45 connector (called a GG45) to achieve this speed. Also in development are standards such as Tera from Siemon. Tera, which does not maintain compatibility with RJ-45, promises transmission frequencies of up to 1200 MHz. 10GBaseT networks are not yet widely available, and may not be able to compete with fibre optic networks.
