For Gigabit Ethernet (1000BASE) the 1000BASE-T1 variant is similar in that it uses PAM-3 for the encoding, but requires (500 MHz capable) Cat-6A cabling due to its 375 MHz bandwidth requirements.
However, 1000Base-T is often erroneously labeled 1000Base-TX. See Ethernet and 10 Gigabit Ethernet. THIS DEFINITION IS FOR PERSONAL USE ONLY. All other reproduction requires permission.
