STRUCTURED CABLING NETWORK CABLES Network cables are used for short distances in local area networks like PCs, routers and switches. On the other hand, optical fibre cables are mainly used for long distances or for applications requiring high bandwidth or electrical isolation. However, network cables are also often used in larger network installations in wiring closets/rack cabinets together with optical fibre network cables. Shielding There are two basic types of network cables: Shielded and unshielded. U Unshielded F Foil shield S Braided shield SF Braided and foil shield Twisted pair Twisted pair ‘Twisted pair’ is a network cable containing crossed-over, twisted, or stranded/solid pairs of cores. This twisting in pairs works as an electrically conductive shield to avoid interference from external cables by magnetic alternating neighbouring pairs of conductors within the cable. Shielded vs. unshielded One of the key factors for using shielded cables is if the cables are used in an environment with a lot of EMI (electromagnetic interference). EMI can cause crosstalk between circuits, resulting in degradation of data, increased errors, and slower transmission rates. Although unshielded UTP cables reduce some EMI, shielded STP cables block interference more effectively. So why not always use shielded cables? First of all, shielded cables are more stiff than unshielded cables and are more difficult to install. They are also more expensive than unshielded cables. The shielded cables often have a larger diameter that takes up more space in the conduit. Unshielded cables actually provide you with faster transmissions in the absence of EMI. Lanview ® 5
