Open the CIPO recordAbstract From the Canadian patent
Implementations of a discontinuous cable shield system and method include a shield having a multitude of separated shield segments dispersed along a length of a cable to reduce crosstalk between signals being transmitted on transmission lines, such as twisted wire pairs of a cable. The separated shield segments can serve as an incomplete patch-worked, discontinuous, 'granulated' or otherwise perforated shield that can have effectiveness when applied as shielding for differential transmission lines such as with twisted wire pairs.
