SHIELDED CABLE WITH UTP PAIR ENVIRONMENT

摘要

A cable includes a spacer surrounding a cable core. The cable core includes four twisted pairs. A separator is disposed amongst the twisted pairs. The separator may be formed with three layers, wherein a middle layer is conductive and outer layers are nonconductive. A jacket surrounds the spacer, and a shielding layer may reside between the jacket and the spacer. The spacer may be formed of plural fibers or a polymer. Preferably, the spacer presents a lower dielectric constant per unit volume than the jacket. The separator may have a tape shape or a plus shape.
