WHAT IS GigE? GigE or Gigabit Ethernet is a member of the family of computer networking and communication standards. The GigabitEthernet standard supports a theoretical maximum data rate of 1 gigabits per second (1 Gbps or 1000Mbps), as definedby the IEEE 802.3-2008 standard. To ensure a high data rate, Gigabit Ethernet workS using unshielded twisted pair (1000BASE-T) copper cable (specifically, the CAT5e and CAT6 cabling standards). pdficonClick to download GigE Trouble Shooting Guide
