  • what is the difference between UTP Cable and STP cable ?

  • UTP (Unshielded Twisted Paired)

    STP (Shielded Twisted Pair)

    The S stands for Shielded, the U stands for Unshielded, and the TP stands for twisted pair for both.

    STP simply has additional shielding material that is used to cancel any external interference that may be introduced at any point in the path of the cable.

    UTP cables have no protection against such interference and its performance is often degraded in its presence.

    Using STP cables ensure that you get the maximum bandwidth from your cabling even if the external condition is less than ideal.

    In terms of usage, UTP cable is the more prevalent and popular cabling that is used in most homes, offices, and even in large scale businesses due to its lower cost. STP is commonly used by large scale companies in high-end applications that require the maximum bandwidth. STP cables are also used in outdoor environments where the cables are exposed to the elements and manmade structures and equipment that may introduce additional interference. Good examples of this would be the telephone/internet cables that run from your home, to the junction box, down to the establishments of your provider or ISP.

    For most common uses, it does not really matter whether you use STP or UTP as both would probably perform well. UTP is the more logical choice as it is cheaper and much easier to find in the majority of computer equipment retailers.
