Telecommunication Cable
Telecommunication Cable
Feature
dc deepcab paired cable products are manufactured in a variety of gage sizes, dimensions, insulation materials, shielding configurations to meet the technical requirments of many different types of systems. Paired cables allow balanced signal transmission,wich results in lower crosstalk through common mode rejection. Due to the improved noise immunity of twisted pair, they generally permit higher data speeds than multi-conductor cables.
