What is the max distance for cat5e cables in 1000Mbps (1 Gigabit) Full Duplex mode?
Quoting from Wikipedia:
1000BASE-T (also known as IEEE 802.3ab) is a standard for gigabit Ethernet over copper wiring.
Each 1000BASE-T network segment can be a maximum length of 100 meters (328 feet), and must use Category 5 cable or better (including Cat 5e and Cat 6).
So it's 100 meters (328 feet).
