CAT 7 features even more stringent specifications for crosstalk and system noise then CAT6. 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.
The cable contains four twisted copper wire pairs, just like the earlier standards.
CAT 7 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.
Also being considered is a non-RJ-45-compatible standard developed by Siemon which forgoes compatibility in exchange for performance, and doubles the transmission frequencies of RJ-45.
