Shielded cabling, of one type or another, has been the preferred cabling infrastructure in many global markets for many years. Cables described as foil screened unshielded twisted-pair (F/UTP) and fully shielded cables with an overall braid screen plus individual foil shielded twisted pairs (S/FTP) are now gaining popularity in markets where unshielded twisted-pair (UTP) cabling has traditionally been the most common solution.
This rise in adoption is tied to the publication of the IEEE standard known as 802.3an 10GBASE-T and this emerging application's sensitivity to noise from adjacent cabling. This noise from adjacent cabling is known as alien crosstalk. Screened and fully shielded 10 Gb/s cabling systems, such as category 6A F/UTP and category 7 S/FTP, are all but immune to the alien crosstalk that presents problems for category 6A UTP cabling. These cabling systems can help reduce the size and cost of pathway spaces due to their smaller diameters.
Even as cabling installers and their clients increasingly enjoy these benefits, confusion surrounding the bonding and grounding of screened and shielded systems has caused some to avoid them. This concern is unfounded, as advances in screened and shielded cabling systems have simplified bonding and grounding methods tremendously. Today, the installation and bonding and grounding/earthing of F/UTP and S/FTP cabling systems requires little additional effort and expertise over UTP installations.
