1. A shielded electrical cable, comprising:
a plurality of conductor sets extending along a length of the cable and arranged and spaced apart from each other along a width of the cable, each conductor set including two or more insulated conductors, at least 90% of a periphery of each conductor set encompassed by, and bonded to, a shielding film; and
a non-conductive polymeric layer covering opposite sides of the plurality of differential pairs and including cover portions and at least one pinched portion arranged such that, in a transverse cross section, the cover portions of the polymeric layer substantially surrounds each of the differential pairs, and the at least one pinched portion of the polymeric layer forms at least one pinched portion of the cable on at least one corresponding lateral side of the cable;
wherein a transverse bending of the cable at a cable location of 90 degrees over an inner radius of at most 5 mm causes an insertion loss of the insulated conductors proximate the cable location to vary by no more than about 0.5 dB from an initial insertion loss measured at the cable location in an unbent configuration, wherein for a frequency range from about 2 GHz to about 20 GHz, a far end cross talk (FEXT) between adjacent conductor sets is less than about −35 dB, and wherein the cable has a skew of less than about 20 psec/meter.
