CAT-3

10BaseT 16MHz Unshielded Used for phone lines

CAT-5

10/100BaseT 100MHz Both two cable pairs seldom used today

CAT-5e

10/100BaseT, Gigabit Ethernet 250MHz Both Has four twisted pairs and heavy duty sheath to help reduce crosstalk.

CAT-6

10/100BaseT, Gigabit Ethernet Up to 250 MHz Both Less crosstalk because it has a plastic core that keeps the twisted pairs separated. CAT -6 and its variations are the most popular category used today.

CAT-6a

10/100BaseT, Gigabit Ethernet, 10Gig Ethernet Up to 500 MHz Both Doubles the frequency of CAT -6. CAT -6a is sometimes unofficially called CAT -6e.

CAT-7

10/100BaseT, Gigabit Ethernet, 10Gig Ethernet Up to 600 MHz Individual pair shield and overall cable shield Shielding almost completely eliminates crosstalk and improves noise reduction. Expected to have a longer life expectancy than previous twisted-pair categories.
