ARJ45 (Augmented Registered Jack 45) is an electronic connector for very high speed applications such as Class F_A installations as defined by the standard ISO/IEC 11801 and 10, 40 and 100 Gigabit Ethernet transmission copper cabling. ARJ45 complies with the international standard IEC 61076-3-110.^[1]

The connector operates in the frequency spectrum between 600 MHz to 5 GHz with twisted shielded pair and twinax cables. ARJ45 utilizes an internal system of Faraday cages to reduce cross talk to 35 dB or better at 5 GHz. Its performance up to 1000 MHz corresponds to category 7A connecting hardware.

Variants include ARJ45 HS, an 8-contact connector, and ARJ45 HD, a 12-contact connector, equivalent to the GG45 with a switch in the jack that activates the alternative pin locations when a Cat7a plug is inserted.
