Abstract: High frequency cable with short twist lays with the insulation thickness of conductors being different from that of others, the thickness of insulation being dependent upon twist lay length so as to achieve a desired characteristic impedance and signal attenuation.

Abstract: A multi-terminal electrical connector having two rows of terminals on one side of a dielectric housing and two rows of terminals on the other side. On one side pairs of terminals are laterally spaced from row to row. Conductors extend through the connector to connect terminals of each pair on one side to terminals of an associated pair on the other side. In one structure, the conductors to alternating conductor pairs on each side are spaced apart laterally of the rows while for the other pairs, the conductors cross over each other. In another structure, the conductors of each of the pairs are spaced laterally and a spacer is provided to cause alternate pairs of untwisted wires to be spaced laterally and the wires of the other pairs to cross over each other. In both structures, the arrangement reduces crosstalk.

Abstract: A telecommunication cable in which pairs of twisted together conductors are spaced apart to minimize capacitance unbalance and cross-talk. A central core member may be provided with the conductor pairs extending around the core member which may have spokes to separate the conductor pairs. Alternatively, the cable jacket has inwardly directed spacers which separate the conductor pins and hold them in recesses defined by the jacket.

Abstract: A binder unit of twenty-five twisted pairs of pulp or paper insulated conductors formed of ring sets and tip sets with a maximum of eight colors for the insulations. The same colors are used in both sets with each conductor set having at least three colors to distinguish certain conductors in each set from one another. Insulation colors of the conductors in one of the sets all have a common style. While conductor insulations of each pair are distinguished visually from one another, each conductor of a certain color and style forms a pair with a conductor, which is visually distinguished from further conductors which are paired with all other conductors of that certain color and style.
