An electromagnetic wave absorption cable comprising an electromagnetic-wave-absorbing tape spirally wound around the inner insulating sheaths surrounding conductor wires, an insulating layer, and an electromagnetic-wave-reflecting layer; the electromagnetic-wave-absorbing tape being constituted by laterally partially overlapped two electromagnetic-wave-absorbing films; a thin metal film of each electromagnetic-wave-absorbing film being provided with large numbers of substantially parallel, intermittent, linear scratches with irregular widths and intervals in plural directions; the linear scratches in each electromagnetic-wave-absorbing film having a crossing angle s of 30-90; the linear scratches in both electromagnetic-wave-absorbing films being crossing; and the total (D.sub.2+D.sub.3) of the longitudinal width D.sub.2 of an overlapped portion of the electromagnetic-wave-absorbing films and the longitudinal width D.sub.3 of an overlapped portion of the electromagnetic-wave-absorbing tape being 30-70% of the longitudinal width D of the electromagnetic-wave-absorbing tape.

Cable foil tape having random or pseudo-random patterns or long pattern lengths of discontinuous metallic shapes and a method for manufacturing such patterned foil tape are provided. In some embodiments, a laser ablation system is used to selectively remove regions or paths in a metallic layer of a foil tape to produce random distributions of randomized shapes, or pseudo-random patterns or long pattern lengths of discontinuous shapes in the metal layer. In some embodiments, the foil tape is double-sided, having a metallic layer on each side of the foil tape, and the laser ablation system is capable of ablating nonconductive pathways into the metallic layer on both sides of the foil tape.

The present disclosure relates to an Ethernet cable for a vehicle, which enables large-capacity data communication and high-speed transmission, required in a network system for a vehicle, on the basis of low voltage differential signaling (LVDS), minimizes the overall outer diameter and weight, and has excellent durability against vibration and excellent electrical characteristics.

A multipair differential signal transmission cable includes a plurality of differential signal transmission cables being bundled and each including two signal conductors as a differential pair covered with an insulation and a first shielding tape conductor provided therearound. The first shielding tape conductor is longitudinally lapped so as to have an overlapping portion in a cable longitudinal direction. The plurality of differential signal transmission cables include at least one or more pairs of two adjacent differential signal transmission cables. The two adjacent differential signal transmission cables are arranged such that the overlapping portion of one of the two adjacent differential signal transmission cables does not face the other of the two adjacent differential signal transmission cables.

Methods of design, manufacture and implementations of balanced twisted pair cables with a barrier tape or shield, with tuned attenuation, impedance, and coupling properties. A filler is included within the cable to separate the pairs and provide a support base for the shield, allowing for optimized ground plane uniformity and stability for tuned attenuation, impedance, and coupling properties. The filler orientation, shape, and size provides support for the shield such that a gap is provided between the shield and the twisted pairs with a given minimum size without increasing the maximum cable core size. The length of arms of the filler may be adjusted to fine-tune the size and shape of this gap and control air-dielectric volume and radial contact or spacing between any pair(s) and the shield, tuning electrical performance characteristics caused by non-linear effects of electromagnetic interactions at short ranges between the pairs, shield, filler, or other components.
