        Shielded vs. unshielded

        One of the key factors for using shielded cables is if   So why not always use shielded cables? First of all,
        the cables are used in an environment with a lot of EMI   shielded cables are more stiff than unshielded cables and

        increased errors, and slower transmission rates.        The shielded cables often have a larger diameter that
        Although unshielded UTP cables reduce some EMI,         takes up more space in the conduit. Unshielded cables
