This cable is manufactured in an oxygen-free environment which drastically reduces signal distortion. Sequential distance markings, anti-snag dispensing slots and easy-to-strip jackets make Binary™ cable a breeze to work with. The conductors are made from oxygen free copper to ensure signal integrity and a lifetime of performance. This Binary™ Category cable includes a layer of polyethylene terephthalate (PET) as well as a layer of Aluminum foil tap; both with 100% coverage. With shielded category cable drastically reduces the chances for cable interference related problems.
