The GG-45 connector is designed for high-speed CAT-7 cable connections. It supports data transmission speeds up to 600 MHz and 10 Gigabit Ethernet over distances of 100 meters. Some key advantages are that it provides backwards compatibility with older connectors while protecting signals better than CAT5e or CAT6 cables. However, CAT-7 may be an unnecessary expense compared to other cable categories for most desktop users.
