Effect of AC Power Line on UTP Cable: Reasons and Reduction Techniques

Data transmission through UTP cabling system is effected by EMI from a nearby Power line through the coupling mechanisms. Today, though UTP cable is the most preferred cabling supporting 10G Ethernet, but it is also the mostly influenced cable by EMI, since it is unshielded. Shielding and Physical Separation are the two most effective methods to avoid EMI. By maintaining a proper separation gap between Power cable and UTP cabling, we can reduce the effect of EMI to a minimum. This paper discusses in detail the different kinds of effects, and analyses different parameters associated. Also the effect reduction strategies and models are discussed.
