http://cisco.num.edu.mn/CCNA_R&S1/course/module4/4.2.1.4/4.2.1.4.html WebTwo main types of shields used for cables are foil and braid. Foil shielding uses a thin foil of aluminum. Foils provides complete coverage for the cables. Since the foil is thin, grounding work is difficult. A braid is another type of shielding used for Shielded Twisted Pair (STP) cables. A braid is a woven mesh of copper or similar metal wires.
WebSep 22, 2024 · Shielded twisted pair (STP) cabling consists of wire pairs twisted around each other to reduce crosstalk. The wires in the pairs are insulated with color-coded plastic, and the pairs collectively are wrapped in foil to reduce EMI. Similar to Coax, around the foil-covered wire pairs is a braided copper mesh to reduce EMI, which is surrounded by ... Web(Choose two.) It typically contains 4 pairs of fiber-optic wires.

Typical coverage ranges from 65 percent to 98 percent. Foil shield — foil shields are constructed of a metallic (typically aluminum) foil with a 1/2-mil thick polyester backing to increase mechanical strength. The shield can be overlapped …
Webmoderately noisy environments, a foil alone may provide adequate protection. In noisier environments, consider braids or foil-braid combinations. 2. Use a cable suited to the application. Cables that experience repeated flexing usually use a spirally wrapped shield rather than a braid. Avoid foil-only shielding on flex cables since
