Shielded Twisted Pair

Shielded Twisted Pair

Twisted pair cabling is a type of wiring in which two conductors of a single circuit are twisted together for the purposes of canceling out electromagnetic interference (EMI) from external sources; for instance, electromagnetic radiation from unshielded twisted pair (UTP) cables, and crosstalk between neighboring pairs. It was invented by Alexander Graham Bell.

Famous quotes containing the words shielded, twisted and/or pair:

    The country is holy: O bide in that country kind,
    Know the green good,
    Under the prayer wheeling moon in the rosy wood
    Be shielded by chant and flower and gay may you
    Lie in grace.
    Dylan Thomas (1914–1953)

    Listen where thou art sitting
    Under the glassy, cool, translucent wave,
    In twisted braids of lilies knitting
    The loose train of thy amber-dropping hair;
    Listen for dear honour’s sake,
    Goddess of the silver lake,
    Listen and save.
    John Milton (1608–1674)

    With two sons born eighteen months apart, I operated mainly on automatic pilot through the ceaseless activity of their early childhood. I remember opening the refrigerator late one night and finding a roll of aluminum foil next to a pair of small red tennies. Certain that I was responsible for the refrigerated shoes, I quickly closed the door and ran upstairs to make sure I had put the babies in their cribs instead of the linen closet.
    Mary Kay Blakely (20th century)
