The GG45 is a connector

Electrical connector

An electrical connector is an electro-mechanical device for joining electrical circuits as an interface using a mechanical assembly. The connection may be temporary, as for portable equipment, require a tool for assembly and removal, or serve as a permanent electrical joint between two wires or...

The cabling system was standardized in 2001 as IEC 60603-7-7, and then selected as a worldwide Category 7 cabling standard within ISO-11801.

GG45 connectors provide backwards compatibility for standard 8P8C (8P8C) connectors in a Category 6 cable

Category 6 cable

Category 6 cable, commonly referred to as Cat 6, is a cable standard for Gigabit Ethernet and other network physical layers that is backward compatible with the Category 5/5e and Category 3 cable standards. Compared with Cat 5 and Cat 5e, Cat 6 features more stringent specifications for crosstalk...

 interface (mode 1), where eight conductors are used for Cat 6 (100/250 MHz) operation.

In addition, GG45 has four additional conductors in the extreme corners that interface with new high-speed Cat. 7 600MHz and Cat 7a 1000MHz networks. The 4 additional conductors are connected to 2 pairs while the other 2 twisted pairs remain connected to the original 8P8C connector's most distant pins: 1 and 2; and 7 and 8. A Category 6 or 6A plug uses the original contact positions, but a Category 7 or 7A plug instead uses the contacts located in the four corners and has a protrusion that activates a switch within the jack for the alternative contact positions. This reduces crosstalk within the connector that higher speed data is sensitive to. The key advantage of the GG45 interface therefore has plenty of headroom combined with the ability to migrate to higher speed service by upgrading to Category 7A patch cords that activate the switch in the jack.
