Which of the following category of UTP cables is specified to be able to handle gigabit Ethernet (1 Gbps)
according to the EIA/TIA-568-B standards?

A.
Category 5e UTP

B.
Category 2 UTP

C.
Category 3 UTP

D.
Category 1e UTP

Explanation:
Category 5 UTP cable provides performance of up to 100 MHz and is suitable for 10BASE-T, 100BASE-TX
(Fast Ethernet), and 1000BASE-T (Gigabit Ethernet). Category 5 was superseded by the category 5e
(enhanced) specification.
Incorrect Answers:
B: The maximum frequency suitable for transmission over Category 2 UTP cable is 4 MHz, and the maximum
bandwidth is 4Mbit/s.
C: Category 3 UTP was widely used in computer networking in the early 1990s for 10BASE-T Ethernet (and to
a lesser extent for 100BaseVG Ethernet, token ring and 100BASE-T4), but from the early 2000s new structured
cable installations were almost invariably built with the higher performing Cat 5e or Cat 6 cable required by
100BASE-TX.
D: The maximum frequency suitable for transmission over Category 1 UTP cable is 1 MHz, but Category 1 is
not considered adequate for data transmission.
