    Unshielded Twisted Pair (UTP) Cable

    Twisted pair cabling comes in two varieties: shielded and unshielded. Unshielded twisted pair (UTP) is the most popular and is generally the best option for school networks.

    The quality of UTP may vary from telephone-grade wire to extremely high-speed cable. The cable has four pairs of wires inside the jacket. Each pair is twisted with a different number of twists per inch to help eliminate interference from adjacent pairs and other electrical devices. The EIA/TIA (Electronic Industry Association/Telecommunication Industry Association) has established standards of UTP and rated five categories of wire.

    Categories of Unshielded Twisted PairTypeUse

    Category 1Voice Only (Telephone Wire)

    Category 2Data to 4 Mbps (LocalTalk)

    Category 3Data to 10 Mbps (Ethernet)

    Category 4Data to 20 Mbps (16 Mbps Token Ring)

    Category 5Data to 100 Mbps (Fast Ethernet)

    One difference between the different categories of UTP is the tightness of the twisting of the copper pairs. The tighter the twisting, the higher the supported transmission rate and the greater the cost per foot. Buy the best cable you can afford; most schools purchase Category 3 or Category 5. Category 5 cable is highly recommended.

    If you are designing a 10 Mbps Ethernet network and are considering the cost savings of buying Category 3 wire instead of Category 5, remember that the Category 5 cable will provide more "room to grow" as transmission technologies increase. Both category 3 and category 5 UTP have a maximum segment length of 100 meters. In Florida, Category 5 cable is required for retrofit grants. 10BaseT refers to the specifications for unshielded twisted pair cable (category 3, 4, or 5) carrying Ethernet signals.

    Shielded Twisted Pair (STP) Cable

    A disadvantage of UTP is that it may be susceptible to radio and electrical frequency interference. Shielded twisted pair (STP) is suitable for environments with electrical interference; however, the extra shielding can make the cables quite bulky. Shielded twisted pair is often used on networks using Token Ring topology.

    Both cable types will work fine for you. STP is a cable that has the twisted signal wires shielded with a foil layer, this prevents electromagnetic interference effecting the network signal and would be used in an 'electrically noisy' environment. UTP is unshielded and is the most common type used. For what you want there would be no benefit from using STP cable, so go for the cheaper UTP option.

    Utp Vs Stp

    STP is Shielded Twisted Pair...it protects the cabling from EMI.

    UTP is Unshielded Twisted Pair...it has no shielding to protect the wiring.

    STP is shielded twisted pair cable, and UTP is unshielded twisted pair cable. UTP is more common in most ethernet-based networks that use CAT-5 or CAT-5E cabling.

    Unshielded Twisted Pair and Shielded Twisted Pair

    Shielded means there is a conductor wrapped around your current carrying cable, it is supposed to block outside electromagnetic signals and reduce noise. It also keeps your signals from leaking into adjacent cables where it might accidently be received by a third party.
