There is provided an improved flat electrical communications cable which includes a plurality of coplaner pairs of elongated, insulated conductors. The pairs of conductors are embedded in a jacket which supports the cable and maintains the spacing among the conductors and pairs. The spacing between conductors in a pair is substantially less than the spacing between each adjacent pair. The jacket is thicker in the regions around each pair and thinner in the regions between each pair, thus forming the valleys and ridges on each side of the jacket. An elongated metal shield covers at least one side of the jacket. The shield conforms to and is contiguous with the valleys and ridges resulting in somewhat of a sinusoidal cross-sectional appearance of the shield. Each conductor includes a dual insulation, the inner insulation being made from a flame retardant material and the outer insulation being made from a different material from the jacket.

An electrical communications cable comprising: at least first and second substantially coplanar pairs of elongated insulated conductors; each conductor in a pair being closer to the other conductor of the pair than to any conductor of adjacent pairs of conductors; an elongated jacket; said pairs being embedded in said jacket; said jacket for supporting the cable and maintaining the spacing of said pairs of conductors; said jacket being thicker in the regions around each pair and thinner in the regions between each pair forming valleys and ridges on each side of the jacket; an elongated metal shield substantially covering at least one side of said jacket; said shield substantially conforming to and being contiguous with the valleys and ridges on at least one side of the said jacket; whereby pair to pair cross-talk is substantially reduced over a flat shielded cable.
