What type of cable is used with 100Base-TX Fast Ethernet?

A.
Fiber-optic cable

B.
Four pairs of Category 3, 4 or 5 unshielded twisted-par (UTP) wires.

C.
Two pairs of Category 5 unshielded twisted-pair (UTP) or Category 1 shielded twisted-pair
(STP) wires.

D.
RG.58 cable.

Explanation:
100BaseTX is a 100-Mbps baseband Fast Ethernet specification using two pairs of
either UTP or STP wiring. The first pair of wires is used to receive data; the second is used to
transmit. To guarantee proper signal timing, a 100BaseTX segment cannot exceed 100 meters in
length. This specification of Ethernet is based on the IEEE 802.3 standard.
