Unshielded Twisted-Pair Cable
» Speed and throughput 10Mbps to 1Gbps» Very low cost» Cable lengths varies (1M – 100M)» Short cables are referred to as “patch
cords”» Consists of 4 twisted pairs using 8 wires inside outer jacket (orange, green, blue,
brown)
UTP Cable Categories» Cat 1 – Telephone wire – not for data» Cat 3 – Used in 10BaseT (up to 10Mbps)» Cat 5 – Data speeds up to 100Mbps» Cat 5e – Data speeds up to 1Gbps (using 2-
pair)» Cat 6 – 4 pairs of 24-gauge copper wires (up to
1Gbps)» Cat 6a – Enhanced performance in high noise
environments (up to 10Gbps)» Most common – Cat 1 (Telephone) Cat 5, 5e, &
6 (Data)
