    None (apart from cost, maybe). STP (Shielded Twisted Pair, vs Unshielded Twisted Pair) is better because it avoids interference between cables. That is why UTP is not used in computer networks, where cables must be used at their optimal bandwith.

    Unshielded twisted pair (UTP) cabling is the most common cable used in computer networking. It is a variant of twisted pair cabling. UTP cables are often called ethernet cables after Ethernet, the most common data networking standard that utilizes UTP cables, although not the most reliable.


    It is a thin, flexible cable that is easy to string between walls.

    Most modern buildings come with CAT 5 UTP already wired into the wall outlets or at least run between the floors.

    Because UTP is small, it does not quickly fill up wiring ducts.

    UTP costs less per foot than any other type of LAN cable.


    Shielded twisted pair is a special kind of copper telephone wiring used in some business installations. An outer covering or shield is added to the ordinary twisted pair telephone wires; the shield functions as a ground.

    US industry has recognized for years that UTP provides substantial

    advantages over STP when considering the following;

    + Installation – Easier to connectorize

    = EMI Performance – Good twisting rates result in sufficient-very good

    behavior for emissions and susceptibility

    + Cable Management – No shield makes cables more flexible and easier

    to handle

    - Bundling can lead to unacceptable levels of ANEXT

    + Isolation – Because cables have no shield, ground management is not

    necessary to prevent loops

    All the best.

    UTP is less expensive, easier to pull and weighs less.
