High-performance, low-cost passive copper cabling remains the preferred alternative for short-reach applications in the data center. However, standard round copper cables can be bulky and consume precious space. A recent innovation in manufacturing technology by 3M has resulted in the development of a uniquely shielded, thin, ribbon-style copper cable. The cable has the ability to fold multiple times and maintain signal integrity, allowing for higher-density racks and space savings. A major barrier to decreasing the size and stiffness of a round cable is inherent in the construction of traditional cable. This is an issue because a round copper cable can extend up to nine inches when routed behind a cabinet. In conventional, twin axial constructions, the shield is applied by wrapping it spirally around the insulated wire pair. This layer is then overwrapped to provide support and retain the primary shield wrap, increasing the stiffness of the pair. Multiple pairs are then cabled and an overall foil and braided shield are typically applied, thus further increasing the cable bulk and stiffness.
