Caution:
Please do not use telephone cables. Telephone cables do not support Ethernet or Fast Ethernet
Twisted-pair cabling comes in various grades, or categories. Category 5 is required for Fast Ethernet, and is also
the most reliable and most commonly used category.
You can buy UTP Category 5 (Unshielded Twisted Pair) Ethernet cabling in precrimped
lengths, or you can crimp your own. Crimping your own can result in faulty connections if the RJ-45 tips are not
attached properly. Precrimped Category 5 cabling is available at most computer retail stores.
The most reliable and commonly used type of Category 5 cabling used is UTP, or "unshielded twisted pair." STP,
or "shielded twisted pair" wiring is only necessary for network environments exposed to excessive amounts of
electromagnetic interference, or EMI. These environments include areas with high sources of electrical power, air
